Since you have had these symptoms for so long, I really doubt you have Paget disease of the nipple.
There are so many types of skin problems, such as allergic reactions, eczema, fungal infection or just dry skin that can appear anywhere on the body, including the breasts, nipples and areolas.
It’s true that Paget Disease of the nipple can show improvement for a while but after a few weeks or even months (not years) the symptoms may reappear and show more serious destruction of the skin. At this stage, the symptoms may include tingling, itching, increased sensitivity, burning, and pain. There may also be discharge from the nipple, and the nipple can appear inverted or flattened against the breast.
My advice to you would be to see a different dermatologist for a second opinion and it wouldn’t hurt to consult a breast Specialist also for a clinical breast exam if it will give you peace of mind.
Thank you so much. My mind is at ease and I will certainly get a 2nd dermatologist opinion.
