It is likely that you're having an allergic reaction which is why it reduced on taking an Avil tablet. I would advise you to visit the ER so that you can get an injection of antihistamines and steroids to control the current allergic reaction. You will require an antihistamine coverage for the next 3 days as well. These following steps may help: - Apply ice over the rashes which may give you some relief - Apply calamine lotion over the rashes after applying ice which will also give some relief. - Avoid itching your body - Keep a close eye on the food you have and the environment you're in due to which this was triggered. Kindly visit the ER at the earliest to get the injections immediately.

Start tablet atarax 2 times a day, calamine lotion for local application
