Why does the ear get red and hot without touch it?
482960
Ear SKIN is highly vascular and highly responsive to both emotional states and body temperature changes.  Blood helps with thermoregulation to protect skin-body from overheating or freezing. Some folks' skin is much more sensitive than others too.  Individuals can also vary on a daily basis how sensitive their own skin is from daily emotions or temp.

I have no clue what that other answer is that someone gave you.  My answer to you is no.  Maybe you have an infected gland, a swollen gland, or an infected sinus.\nGo to the drug store and get the eardrops that are for ear aches.  It doesn't cost much and it works.  \nMeanwhile, just to be on the safe side, take a couple of motrin, and / or tylenol.  Make sure you're not running a temp.  If you're running a temp then you can be sure there's an infection brewing somewhere.  If all the above fails to help you, then call your doctor and be seen.\nHope you feel better.

its the other way round. a thing is hot if its molecules are moving with a higher thermal velocity (prop to T^1/2). if you heat something its molecular vibrations go up in turn increasing its temperature.

Sounds like your cold got "in your ear".  Glad you are seeing the doctor.  You may need antibiotics to clear this up.  If left untreated, it could potentially effect your hearing.  Sounds like you caught it in time.  (No pun intended).  ; )

The back pain can be from your kidneys not getting enough water. The sore throat can be anything from allergy to infection. If you develop a fever, worry alot cuz then you for sure have an infection. See the doctor...if you have a temperature. Ear ache can be infection or the after trauma of someone hitting you or you bumping into something.\n\nFor ear pain boil a garlic, mush it and stick it in your ear, garlic cures infections (some). Note: make note of your menstrual cycle for the back pain as well.

Just red, with no other symptoms? That is bizarre (MD here). Gotta suspect something vascular as the primary cause, but can't tell much given that we know nothing of your broader history (immediate and past).\n\nGood luck. If any redness begins to spread upward towards the armpit, especially if there are streaks of red going up your arm, and particularly if you develop a fever, then get your behind to your doc or your local ER, OK?

this actually depends on where you actually keep your hands. Some may get excited when touching the ears, for some it may be hip. Some may not get excited on these things.

Please please go see a doctor immediately.   It could be something as simple as an inner ear infection ... or something as serious as a stroke.   Don't wait ... call now.

The noise you're describing is known as pulsatile tinnitus, and is probably generated by turbulence of the blood flow in the vessels near the ear. In some people this is normal, but there is also a possibility of this being due to an abnormality in the blood vessels near the ear (such as an aneurysm or an AVM). You should consult an ENT surgeon for further investigation, especially since in your case it has only been present for a week, and is associated with pain in the ear.

different reasons: sometimes fluid gets trapped in the middle ear causing it to ache.  other times, bacteria travel up the tubes to the ears from the throat, causing an infection in the middle ear. this leads to swelling and pain.

Yes, it could be a skin infection, called cellulitis. Apart from the redness, does it feel warmer to touch than the normal areas of your skin, and do you have a temperature?

Could be inner ear or high blood pressure

Some people have ear infections when it is cold weather with out noticing. But your ears are sensitive and the cold air that goes in freezes well makes your ear colder and because our ears are so sensitive the cold makes it fel like glass wich makes our ear ache even worse with lots of  noise around you ! hypercondriac another fact that causes your ear to ache when its cold is that you are just a  lol jokin hope this helped

the ear actually hurts if the sound "intensity" is greater than 120 decibels

The itching could be due to either infection, dry skin or allergy. \nI would go with infection since you have one.\nUse ALCOHOL to clean around the posts not peroxide as peroxide has a healing agent in it and you do not want the ears to close until the infection is gone.\nIf the earring you have in now is surgical steel that is good from an allergy standpoint.  Check the grade of the steel (you can find out about grades from a google search) and make sure you are using good quality.  If you have cleared up the infection (which can be caused by allergy irritation btw) and it still itches, you might want to switch metals.  I know my Aunt is allergic to nickle, and I am allergic to gold, so we have to get post covers (they are like little condoms for your earrings LOL)  I think they are called aller ears or something like that.  Most Claire's and cheapie earring stores have them...hmmm, I wonder if there is a connection there LOL
