What you are describing could be a patch of eczema or even psoriasis . If would need to be examined and evaluated to advice proper treatment.. Eczema and psoriasis take time to resolve and more often than not the creams and treatment have to be continued for a long duration till your skin stops reacting. Also, even if it resolves, it can develop later also again. Hence, need to treat it based on the current situation and degree of severity. Kindly come in for a consultation so proper assessment can be done, or you can visit a qualified dermatologist in your vicinity. Hope this was helpful.
