You are having recurrent eczema.
You have been having this condition for a long time and must have already undergone many different sorts of treatment.
I am not going to give you a prescription, that cannot be done on the net without examining you.
I can however give you medical advise which will help you.
Since this problem is not controlled with your previous treatments, I will advise you to consult your dermatologist again and discuss some treatments which can help you:
Long term oral steroid: a long term steroid like oral Prednisolone is indicated for you and will help you greatly.
Retinoids: systemic Retinoids can be given for this and will be curative
Immunosuppressants: Immunosuppressants like Tacrolimus and Pimecrolimus are the mainstay in intractable eczema
Light therapy: like Ultraviolet and Grenz Ray therapy.
These are the three therapies which your dermatologist can prescribe for you and which will cure you.
Meanwhile follow the following steps for this:
Antihistaminic: Continue the antiallergics like Avil
Avoid sunlight: This is most important. Avoid going out into the sun as far as possible. If you have to go out, use a wide brimmed hat and long sleeved dresses and pants. Sunscreen is a must – use sunscreens with 50% SPF or more.
Steroid Ointments: Apply 1% hydrocortisone (OTC) twice daily on the areas for 1 month.
Emollients: Use an emollient, a hand cream twice daily. Combine the Emollient with the Hydrocortisone ointment or you can also alternate the two.
Avoiding the irritant: If some irritant can be identified, then it should be avoided.
These steps will help, but also discuss with a dermatologist about the treatments I suggested.
