Just need some help trying to figure things out. I was diagnosed with RRMS in 2010, had the liberation procedure done in 2011. I had headaches prior to the surgery but they would come and go and not be that severe. But since the end of November I've had a head ache that does not go away and gets worse during my monthly visitor. Tylenol and Advil do nothing to help with the pain. The head ache is weird because its only on the left side of my head and sometimes it wakes me at night. I have had a CT scan and was happy they found my brain but nothing extra. So now I am going for an MRI. Has anyone else out there had this problem or any one with anything that might help I would appreciate the information.
