Hi sissy I also have pcs symptoms for about a year and a half. I have been to 4 neurologist's and everyone of them said something different. Have you ever tried migraine meds. It did not work for me yet. There was an article in the Chicago Tribune about migraines with and without the aching of the head. It also said how hard it is for docs to diagnose this. Just a thought, I try everything. I also am seeing a dizzy specialist and he has me doing these bppv exercises. This helped TONS with one of the dizziness feelings. I think I have a couple of dizzy stuff going on one is cured the other the doc basically told me I am going to have to live with it. I have an appointment with a different doc and he thinks they are migraines but none of the meds have worked. I hope that he prescribes a different type, that might be the answer. Good luck.
