I had bunion surgery and y doctor prescribed cordran tape. i have been wearing it consecutively for days and it seem to have caused a reaction. it left like a scaley surface. will this reaction go away??

I would be more concerned why the doctor has been having you use tape????? You did not specify how many days post op you are. I used to say if you do not have the correction at the time of surgery , you will not achieve correction later on. If it is more than three weeks soft tissue is mostly healed . Over the counter cortisone applied twice daily should heal the dermatitis
