Hi there. In your specific case, this needs to be visualised by a dermatologist
, asessed & treated as stop gap measures are apparently not effective. If you should choose to, please use the premier 'ask-a-doctor' option on this portal & contact me with further details about your rash
, investigations if any & clear photographs of the rash & will be happy to assist further. In the interim, do take an antihistamine eg. Fexofenadine180mg in a once/day dose to allay symptoms. Cheers & Good luck & wish you a speedy recovery.
