Hello,
You are suffering from a condition called 'Contact dermatitis'. This occurs due to an allergic reaction when the skin comes in contact with a foreign substance.
Since the reaction is due to a reaction to a substance that has acted as an irritant on your skin, you must use a corticosteroid to bring it down. An ointment containing Betamethasone Diproprionate available as Diprolene ( a prescription drug) will work well. Lotriderm ointment with a lesser strength of betamethasone is also available as an OTC medicine , but this contains an antifungal medicine also.
Apply ice packs on the skin to cool it. You can also appy calamine lotion as a cooling agent. Antihistaminics like benadryl must be taken orally.
If the redness does not go away in 1 weeks time, please see a ddermatologist again.
Please see the following for more details on contact dermatitis:
