Ive had issues with my bellybutton for about 2 years now, i had granulation tissue inside and went to a surgeon and i got better but i still feel discomfort and pain when i try to exercise, would a dermatologist know what to do? i want it to heal?

A Dermatologist would be the best doctor to have it seen by. They would then develop a plan to treat and heal.

You can go to a dermatologist to have it evaluated to see if there is anything further that can be done. A dermatologist could definitely do an evaluation and discuss treatment options with you and then you can decide the best way to proceed. Good luck to you!
