I had the same problem. Wherever I had surgeries, they came back. I went to a dermatologist that does needling for them. It has made a huge difference. The surgeries cause more inflammation that then causes more flare ups. This new doctor doesn’t even do biopsies on them, she just looks and puts a couple needles of a steroid/chemo combination into the area. Ask for a doctor that does needling! It could change everything, and I hope it works for you as well as it has for me.
