Why is it that immediately after an injury, you don't feel as much pain as hours later?

This is a very common occurrence, and can even happen with (severe trauma. I was just involved in a major auto accident Though I felt alright physically that day, the pain kicked in the next day and worsened over the following week or so. It's getting better, but my neck still hurts. Yes, the third site I listed (among others) does say that adrenaline can cause you not to feel pain. But there are other factors.\n\nThe doctor says this is because swelling doesn't occur right away, but when it does, it causes pain (hence the use of ice, to reduce it).\n\nAccording to the site below (painreliever.com): \n\nA. Swelling is a natural inflammatory reaction of the body to injury. It occurs when damage occurs to the small blood vessels called capillaries which leak fluid into the surrounding tissue. The increased blood flow is largely responsible for the telltale symptoms of inflammation. The rush of warm blood causes redness, heat and swelling. At the same time, pressure from the swelling and the accumulation of immune cells, along with the destructive chemicals released by the cells, irritate local nerve endings and cause pain.\n\nThree major events occur during the inflammatory response:\n\n    * Vasodialation-An increased blood supply to the tissue which signifies that tissue is ''in danger''.\n    * Increased capillary permeability- The capillaries permit larger molecules than usual to all of the cells needed for healing to get to the site faster.\n    * Infection Protection-The cells used to help fight infection seep out of the capillaries and into the injured tissue to start fighting any infection and cleaning up the injured sites bi-products. \n\nThese events signify the importance of the swelling process."\n\nThe first site suggests that endorphin es are released during significant events for the body (whether pleasure OR pain) and can control pain for awhile. This, too, would stop you from feeling pain until the endorphin es wore off. \n\nThere are many sites on how to treat injury and pain. Ice is key in the first day or so, followed by heat alternating w/ice, and anti-inflammatories like ibuprofen, or stronger Rx drugs if the injury is more severe.\n\nSince ligaments and muscles are often torn and swelling takes place at the site, it's important to rest and let healing take place. However, this can take months sometimes. \n\nIf the pain continues, I'd see a chiropractor, to readjust the various bone that were knocked out of place during the accident. This should also relieve the pain caused by pressure on nerves.\n\nGood luck to both of us, eh?

If you recently injured it is likely in an inflamed stated i.e. red, hot, swollen, and painful.  So the best way to handle that for the next few days is RICE (rest ice compression elevation) \nrest- take it easy respect pain and don’t do any thing that hurts it you can make it worse, but you should still be active because too little activity can cause your muscles to atrophy and cause more problems besides your knee will like the blood flow just be smart and slow\nIce - get an ice pack and use it for about 5-15/hour minutes whenever the pain goes away and you have a little bit of a numbing effect ice is a natural anti-inflammatory.\nCompression maybe an ace bandage around the knee NOT VERY TIGHT! You can wrap it while you ice to help limit swelling\nElevation when you ice or are just kicking back elevate your knee but that only works when you get the knee higher than your heart, elevating will help with swelling as well

You might be suffering from muscle tension ya know.  If blood cannot steadily flow through the major vessels in your wrist, it'll cause problems mainly in similarity with those you have.  If it feels as if its more than just an acute type of pain, you might have a mild case of scar tissue. other than that, i don't know.

Ahh sounds like a definate case of torn blood vessel. The brusing gave it away. Most blood vessels have little innervation, so when their torn or damaged you usually don't feel it. The swelling afterward was due to a buildup of blood under the tissue where the tear took place. Most pain from a ruptured vessel comes from the pressure the blood puts on surrounding tissue. Sometimes though the pressure is just right and no pain can be felt if there is enough room for the blood to drain to. As long as you still have sensation on your hand and good grip I think I wouldn't be worried to much, but if you are worried please see your Dr. They can further evaluate any results and see what else if anything needs to be done. Good Luck!

Yes it is after all the body needs time to heal it self and everyone heals better than others but if its still numb after 10 days go back to the dr.

It depends on whether it is just stretched or if it's partially or wholly torn, but if the severity of the injury and the ability to keep the injured body part immoble for a period is equal, the healing time would also be more or less the same.

try heat 1st...it helps relax the muscles in case you may have a pinched nerve (which is kinda what it sounds like) or maybe some bengay, but if it goes longer than about 3 or 4 days...go to the dr...you may have done something worse...perhaps a herniation or a slipped disk.

Immediately after the bruise is incurred (up to 24 hrs.):  Apply cold.  This minimizes leakage of blood into the surrounding tissues.\n\nAfter 24 hrs.:  Apply heat.  This speeds the inflammatory processes that break down the blood that has leaked into the surrounding tissues.

All it takes is a fall in the right location, just the right way.  My brother ruptured his spleen rolling down a hill when he banged into a tree.  It wasn't that big a deal until he could hardly move the next morning.  If you have significant pain then go to the emergency room and seek medical attention.

Going to Yahoo! answers to get mostly lay people's opinion on medical conditions that they can not see or ask questions about...just take the answers with a grain of salt.\n\nAlthough you say you had, you probably never really did pull a muscle before.  But you have now.  The symptoms you describe are typical of a pulled muscle (not a strain which often involve ligaments where its a little painful for a couple days and then all better - no bruise)  In this case, the muscle ruptures and a very significant bruise shows up several days after the fact (Often causing the skin to be tender and firm).  \n\nIt takes about a month to recover.  The bruising you see on the other side of your foot I think is probably a dependent hematoma (a bruise that shows up at a place lower than the injury because gravity pulls the blood down).  Any place there is a collection of free blood, which occupies space, there may be some tenderness.  I doubt that the muscle relaxer is very helpful two weeks after the fact.  Anti inflamatories might be helpful (like Alieve or Ibuprofen) or even Tylenol if you don't get along with the others.  Rest it.  You can use heat and ice combinations.  Do some gentle stretching.\n\nGood luck.

You could have strained too hard and caused a little tear, you could have a fistula,polyps,or hemorroids. If you are experience pain that lasts longer than a day or two or is accompained with blood you should see a doctor.

Honestly,  If the pain just started yesterday after lifting some boxes and isn't horrifically bad, then you should give it a few days.  90% of all back problems self-resolve within 10 days to 2 weeks regardless of the actual condition or the type of injury, provided it wasn't a major trauma.  If you are not opposed to taking over-the-counter meds, try Alleve, 2 in the morning and 1 in the afternoon, each day for 7-10 days.  Ice is usually better immediately after injury because it decreases any associated swelling and numbs the nerve endings (20 minutes, every 4-6 hours during the day).  Also, try to stay moderately active with your typical daily routine but of course, no lifting or recreational sports until your are better.\n\nIf you are not significantly improved within 7 days (at least a  50%-75% decrease in symptoms) then make an appointment to see your physician.  If the physician recommends rehab, ask to be referred to an experienced physical therapist that specializes in manual therapy and/or spine care.  Also, do not be afraid to contact several rehab centers and ask if they have a therapist that specializes in spine care but you should really look for one that is either in private practice or manages a small facility.  I do NOT recommend Novacare and/or HealthSouth as most of these facilities do NOT allow their therapist control over their own schedule and you will not likely be able to see the same therapist from visit to visit, which is poor medicine dictated by corporate interest.  I also do NOT recommend chiropractic, there may be some decent chiros out there but their profession is so littered with quacks and money grubbers that it is a big gamble.

Initially after a work out your brain will release endorphins as a pain reliever to help your body not feel pain as it heals, mostly during sleep. It also makes you feel very good.\n\nThat is why most typically feel better when they are in shape or getting there. \n\nIt only last certain periods of time, usually for a day or two. When it runs out (usually a day after a good workout) you will feel it. Your body is the same, but you feel it more two days later because the endorphins wear off.\n\nMake sure you stay hydrated constantly hours before, just before, during, just after, and hours after your work out. \n\nEAT A BANANA BEFORE YOUR WORKOUT!!!!\nThe potassium will give a very noticable boost, and help with cramps.\n\nEAT SOMETHING SALTY AFTER YOUR WORKOUT!!!!!!\nThe salt will trap water into your muscles that move in when your muscles stretch and keep it there, maintaining your swollen state.\n\nNEVER EVER DRINK CAFFEINE OR ALCOHOL AFTER!!!!\nThey sap water from you body and you will ruin your workout as if you never did it.

Pain is the signal for you not to move the affetced part. There is a hormone called endorphin which is a bodies own pain killer. When you are active or awake this hormone level in the blood is high and you feel less pain, but when you become tired or go to sleep the hormone level goes down and you feel more pain. And the other cause is the production of toxins, in the night body tissues start to regenerate to heel the wound or to replace the damaged tissue, in this process cells uses a lot of energy and produces toxins as by products including substance P which is a potent pain mediator. To have a nice sleep, sleep in cold enviorment. Never try hot water packs ain affetced parts ehen you go to bed.

You need to talk to your surgeon or attending physician. There are some activities that they will recommend that you do not participate in for a specific amount of time due to the possibility of re-injury. You're still in the recovery phase and while you shouldn't "sit home and feel sorry for yourself" patience really is a virtue. You're still healing.\n\nGood luck and glad to hear that you're doing well!

Because your skin is more sensitive at that time, the pain receptors in the body are more sensitive as well
