I had brain surgery in 2000 for cavernous angioma. I had migraine attacks for years prior to that, and once I had the surgery, they did improve. However, the past three years they have been getting worse. All of my test results always come back normal with sometimes having mild irritation in my ‘surgery-bed’. I am curious to know what your surgery for scar tissue was for. I have addressed this with my doctors a few times, and they will never give me any answers about it. I am wondering if some of my 3x’s per week headaches could be related to scar tissue. Any information you could give would help greatly.
