Sorry to hear you must be very frustrated. When I had bad headaches and ended up in hospital they put me in a dark room, cool cloth over my forehead, pillow under my feet and made me drink lots of liquids. I believe you also need to take something that has an anti inflammatory in it.
I also found some very strong magnets that I use know for almost any type of pain. I may look like a monster with bolts sticking out but the blood rushed to the pain, reduces the swelling and I feel no pain. do your research on magnetic energy this may help. Good luck. Feel better soon
