Hello, Welcome to healthcare magic. From your history and description, it seems to me that yo may have developed an allergy to Ibuprofen. It is a common drug known to cause allergies. I suggest that you avoid taking ibuprofen in the future. For the current episode, you could take antihistamine like Loratidine in the morning and Benadryl at bedtime. You could apply a mild steroid cream like hydrocortisone or fluticosone on the itchy areas twice a day for 5-7 days. However, if you develop blotchy rashes and oral ulcers / redness of eyes, please consult a dermatologist as this could indicate a more serious drug rash. Hope this helps you. Take care.
