Today (10/22/09) I developed a sudden itchy rash that turned the skin on my arms and knees hot and bright pink. There are small portions of raised white skin that look similar to mosquito bites of different sizes, but I haven't seen bugs recently (it's cold out) and I don't remember being bitten. I change my sheets and towels once a week.
I have been sick with two separate mild common colds for about two weeks (the second was picked up in Canada a week ago; I live in Pennsylvania). I haven't eaten anything unusual in the past few weeks.
One possible cause is an allergic reaction to a birth control pill I started taking on Sunday (10/18/09), but it's been about five days since then and I haven't felt anything else unusual.
The symptoms of the cold I have are mild sore throat, runny nose, cough, fatigue, and mild upset stomach.
I took an antihistamine and used lotion on my skin an hour ago, and neither have had much effect.
I am 17 years old and female.
Thanks for any feedback!
