What would cause bleeding under the large toe nail?

You may have a blood-filled blister under your nail.  I've had them many times from playing sports, from stopping quickly (basketball and floor hockey).  Your nail may turn black-and-blue and fall off.  Don't worry, it'll grow back.

A hang nail isn't really a nail, it's a small piece of torn skin near a nail.  They're usually caused by dry skin or nail biting, so can appear at any time.

The nail is important in protecting the sensitive nerve-endings, and this needs to be addressed with a doctor in order to help her develop normally.\n\nPossible causes:\n1. Fungal infection.\n2. Nervous system disorder.\n3. Nutritional deficiency.\n4. Mineral deficiency.\n5. Genetics.\n6. Compulsive behavior (Tourette's - no, not as in swearing; most people with Tourette's compulsively pick at some part of the body)\n7. Defect in the nailbed or nail matrix.\n\nStart with a pediatrician and have him or her refer you to a good dermatologist.

Standing too long on your feet. Walking alot. Ill fitting shoes. Poor circulation. Just some of many reasons. If it persists see a podiatrist.:)

I am so glad you asked.\nEpson salt and really hot water-soak your infected foot. If you get them concurrently like I had in the past, go to the podiatrist, have him to a procedure on you that consists of numbing your toe up, cutting the nail off, jabbing huge q-tips with a chemical called phenyll on them down  into your  sides of the toe, and wrapping them up and wabam, ur done. Umm, I made that sounds REALLY painnful, but it is not at all, I watched the whole thing conscious, but then again, I was numbed up. Have fun, andif  you have any further questions email me at lawguy04_1984@hotmail.com... :-)

That's called Mortens toe. Don't know why it happens.

If the nail is still connected to the finger do not try to remove it.\n\nAll you have is the equivalent of a bruise but on your nail.  Most of the blood will be absorbed back into your finger and any that is left will grow out with the nail - it won't look very pretty but should be painless.\n\nIf the nail is hanging off go and see a medical professional - They will make a call as to whether it is best to remove, some or all of, the nail and will do it such a way so as to not to cause infection.  \n\nIf you try to do this yourself you could also end up changing the growth pattern of the nail and end up with an ingrown finger nail.

Am I missing something, everyone is telling you to bandage it and use antibiotic ointments but I don't see where you cut anything.\nIf you are bleeding underneath the nail as you say it truly will hurt A LOT!  \nElevate your hand above heart level. So you can sit with your elbow on a desk and hold your hand in the air, or hold your hand up while arm is on the arm of chair, you get the idea.  You can use an icepack as well. It will help stop the bleeding, decrease swelling and decrease pain. But don't put hand down to put ice on, the elevation is more important until the bleeding stops.\n\nIf the bleeding stops and the swelling stops and the discomfort is something you can function with you don't need to do anything further. BUT:\n\nNow for the part you probably won't like. The problem with this type of injury is there is no where for the blood to go so the end of your finger gets swollen with blood and then more swollen with normal tissue swelling from an injury. If the swelling becomes too severe or if the pain becomes too much for you go to the ER or to an urgent care. What they will do is use a small drill and put a hole through the nail to release the pressure. \nNow that you are done saying NO WAY, let me tell you that most of my patients report immediate pain relief once this is done. And a lot of them don't even really think it hurts much because with all the pressure they don't really feel it. As an observer of many of these procedures I would recommend not letting them numb the end of your finger to do this. No I am not a sadist, it is just that the numbing procedure will cause you more pain and take longer than the actual drilling.\nYou need to do this at the ER or Urgent care and not you doctors office because offices don't have a drill. Most of them will send you on to an ER if they have any compassion. Others will tell you they can do it just as well with a needle.  While it is true pushing a needle through will accomplish the same thing it will hurt a lot more because of the force to push it through.\nNow as a final solution if you are really brave, you can sterilize a needle with heat or alcohol and make a hole through the nail yourself.  I only say this because my sons and brother worked in  construction for years and have hit their fingers with hammers more times than I can count. They got tired of going to the ER so they started doing it themselves.  I had the supplies and provided instruction but I couldn't bring myself to push it through myself.\n\nAny way, if you make a hole in one way or another then you will need to keep the finger clean and covered for a few days to allow it to heal. Keep in mind no matter what you decide to do about making or not making a hole you might lose the fingernail at some point.

It sounds like you have an ingrown toenail and the only cure for that is to have it removed.  I don't know what color it is, but if it has gotten thick and yellow, then you probably also have a fungus infection in the nail.  If the nail is gray and the toe around it is bright honking red, then there is a chance that you have a staph infection.  Either way, a trip to the doctor is in order, unless you can pull it out yourself and have access to antibiotics.  Good luck.

Since there are a number of conditions that can lead to the loss of a toenail, please do not try to self-diagnose or diagnose from what people tell you at this site.\n\nYou need to go to your primary care doctor, who may order some tests or who may be able to diagnose your case and prescribe a remedy by just looking at your toe.

As a teenager ( a couple of years ago! ) I smashed my finger in the car door.  It bled terribly.  My uncle took a sterilized knife and bore a small hole into the nail to relieve the pressure.  It remained horribly purple for weeks and the nail came off.  Another nail replaced it, although it did take a while.

It's hard to tell if this is what you mean, but "splinter hemorrhages" are dark splinter-shaped bruises under the fingernails.  This could be a sign of something serious, like a heart infection.  Then again, "splinters" could be 1000 other things as well.

Tissue or cotton balls in the toe. :)

Your nails have to have oxygen because the under lying part is still alive.  The top is dead cells.  Without the oxygen it can get fungus or infections.
