Hi there. Please re-visit that doctor. You may require a change of cream. The lesion on the back appears unrelated to the groin problem. However, in the interim while waiting for the doctor, please do try to apply the same ointment on your back. Do hope this helps. Am guessing the cream given was a multipurpose general cream. A moisturiser like aloevera
that is 'natural' may be added to your regime. Do hope it helps , else feel free to contact us through our 'ask a doctor' icon & upload photographs of your lesions please. Cheers & Godspeed!
