Other insect bite, insect sting, ingrown hair, other unknown puncture or abrasion.\n\nIt could be a lot of different things. If it's "like" a spider bite, it could be a spider bite. There doesn't have to be two fang marks. The bite could be very tiny with a large welt as a result of the reaction to the bite.

I would say if it's been a while since you got up and started moving around, the feeling should be back... I would call your doctor.  It could've been like a pin stroke.

Could be for several reasons - first thing to do is check out your relatives. It could run in the family.\nThen you should check how the hair falls out. If there are circle shaped spots where the hair is gone - then you should see a doc about it.

Pretty common. I had it when I was about 9 or 10. It was embarassing, but it happens to alot of kids.\nI remember my mom freaking out. She practically bobbed my hair short and bought the special shampoo for head lice.

If the tick was attached so that you had to pull it off, it did in fact bite you.  The bite is painless, and serves only to anchor the head of the tick in tissue so it can suck blood.  You should have someone look to see if the head of the tick is till in your scalp, as they often break off when a tick is removed.  Have someone check your scalp for the next week or so for redness or swelling, which might indicate Lyme disease.  You might also call your doctor and see if you need to start a course of antibiotics as a precautionary measure.

Be careful. I learned in anatomy that there's a chemical in paper that's the same chemical in our bodies that causes hair loss. So watch out for that.\nYou may have a nervous disorder that causes you to chew on the paper.

This is a genuine medical condition known as trichotillomania. Trichotillomania is an Impulse Control Disorder characterized by the repeated pulling out of one's own hair or eyelashes and eyebrows. It can be treated and there are a number of on line help/support groups. See your family doctor for referral to a psychologist if you don't have any luck with a web search - it sounds like you have tried your best on your own and to avoid permanent hair loss it would be useful to seek professional help.

When we feel cold or frightened, tiny bumps causing a tingling sensation appear on our skin. Attached to each hair inside the skin is a tiny muscle. When you get scared or feel the cold, messages go shooting off from nerve endings that pick up the cold feeling. In a flash, signals come back to the muscles, and as a result each muscle gets taut. The skin around each hair also gets pulled up. The result is little bumps.
