Did the tick have a white circle on it's back?  If not don't worry.\n\nthe redness will go away.

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?

try changing your soap or towel.  I doubt it is the water because then your hand would itch after washing your hand or doing anything in tap water.  IF the itching stops or continues with one gone or the other gone, you know you have you culprit

It could be several things, really. It could be an infected hair follicle, a wart, a really determined pimple, or many other things. Does it bleed? Does it itch? Is it painful when you leave it alone? \n\nDon't pick at it. See your dermatologist. Good luck. :)

Any skin you press will make a indentation for a while, try drinking more Water. Just quit pressing to see if it makes a mark..

It could be an allergic reaction to something you came into contact with.  I can't tell you what it is since I don't know what it looks like or anything else.  You should see a doctor as soon as you can.  I'm sure he or she will be able to figure it out and help you get some relief from the pain.

It means you've rubbed the feeling away from it give it a rest for a week or so and try again.    Try rubbing lotion in.   If you use rough hands it is hard to get the same sensation with something soft and warm

First assess the damage.  Is it just a little red mark?  Put it under cool running water, put a moist bandage over it (loosely), and that's all that's needed.  If you have aloe vera or burn spray, use that before bandaging.\n\nIs it blistered and/or seeping fluids?  Or is it white or charred?  Put a dry bandage over it (again, not tight) and take her to the ER.  If you aren't old enough to drive and there's no one who can drive you, then call an ambulance.

I don't have an answer but I suggest you get it checked out if it dosen't disappear in a couple of days cause you never know what it can become.

It has to do with feedback. Whether you acknowledge it consciously or not, you are aware of the movements of your different body parts, what they are doing, etc, even if your eyes are closed. Even if you are deaf. If I remember right, this is called propiocentrics (don't quote me though). So if you touch your own arm, you not only feel your arm being touched, you feel that your hand is touching your arm, which confirms that it is you doing the touching. This is feedback.\n\nThis is why a numb limb can be very creepy. Ever wake up with your arm asleep and think someone else's arm is hanging over you? It's a rather common occurence. The feeling of numbness results partly from a lack of feedback. If your arm is numb, you can't confirm that you are touching that arm (unless you look, but that's only a substitute for sensory feebback).\n\nSo if you will notice, you can be tickled by a lot of different things. Feathers, hands, pretty muchh anything that's not too hard and pointy poking you the right way will tickle, except for your own hands. For some reason, this feedback interrupts the tickle reflex. I don't know why, but it could be because tickling is a social activity. It mihgt be something meant to be used in play, to strengthen social bonds, or it might be a way the body warns you it is being attacked. Either way, it would serve no purpose to tickle yourself. Those are just guesses though (and not very good ones).\n\nThe simplest answer is sensory feedback inhibits the tickle reflex.

It could be an allergic reaction or a yeast infection. See your doctor A.S.A.P. it could lead to other infections. What ever you do. DO NOT SCRATCH.. Scratching can lead to heavy discharge and other infections.

dudue take this seriuosly "you'er detoriating!"\nok just kidding,you shed dead cells evryday (yes cell are to small to see), here's the catch sometimes our skin just peels as an new layer takes it's place, so hurray you got new skin! ok that was too hype but it's normal, it could be that or an alergic reaction to detergent, dishwashing liquid or any thing, but if it doesn't hurt, itch or bleed then there's nothing to worry about

The skin in the body is being irritated by some cause. When you scratch your itch, you scratch you skin causing some of the itch to go away.

You really need to see a Doctor. It could be a spider bite.\nIt the meantime if it's red and hot you can put a wet cloth\non it. You don't want to let something like that go.
