I am very overweight and have this patch on my inner thigh of each leg. the skin looks like alligator skin and then leads to a section that almost has the surface of corn on the cob and it is very pink. there is one section that seems to be splitting apart. it is painful. I sometimes put A&D on it and that temporarily helps it. what kind of doctor should I go to? dermatologist, obgyn, primary care doc, I just do not know. it is very embarrassing. What is it.
