For the last 3 days I have had small bumps on both elbow and knee, area is red and when skin is pinched the bums turn white and you can notice a pin size hole in center of each bump. not painful at all but itchy, when i itch , some bleed very little. No puss. I have put Hydrocortisone Cream on it , helps itching but can t let clothing touch or it starts to itch. What is this? I have had it before on elbows only, never knees. 44 yrs old Male. No allergies to any pollen, food or drugs. Yes i know Rare and lucky. :) TY.
Howell come to ChatDoctorThis could be autoimmune response and this is happening in collagen disease, condition is almost self limiting and seldom need treatment and the option would be antihistamine or steroid (But one must be qualified for this, age and gender is matter here) hope this information helps, take care.
