Developed rashes, redness and blotchiness, no itching, cough. Tried benadryl. Is it an allergic reaction?
Patient: My son has been developing a rash that is red and blotchy, but not raised.  He says it does not hurt or itch and it goes away using children's benydryl.  He also has had congestion and a mild cough lately.  The rash is only on areas not covered by clothing.  It is also on his ears.  It seems aggravated by headphones, is it possible that a brand new pair of headphones is causing an allergic reaction? Doctor: Hi yes there is a possibility of brand new earphones causing the rash but usually allergic rash is itchy.it think in ur case it can be due to sun allergy or milaria due to excessive sweating .even then rule out other viral rashes where itching is minimal.use of benadryl tablet along with vitamin c chewable tablet can cure the condition.
