hi -the skin rash you have is mostly allergic in origin .It becomes important to break the allergy cycle .while tackling such condition. any chlorpfenaraminne maliateor levocetrizine preparations along with betmethasone tabs(if needed) &ointments are usually priscribed. The next stage is to recognise &avoid sourse of allergy. Here allergy detection tests&desensatisation thereafter if needed. -The anathere cause for the such a rash is Scabies infection. Here the Rashes are more in skin folds, seen in family members/friends because it spreds by skin contact.THey are rarely on face. That s why I have kept is as a 2nd possibility.You need to consult a skin specialist incase of doubt. Hope the advice given is helpful to you. Thank you.
