had a migraine so bad for a week off and on...with little releif. I had to go to the ER for injections of pain meds. Now my doctor has put me on Prednisone for the migraines. I've been on them 2 days. I have still been getting migraines. The only thing I do is take motrin or Xanax or Vicodin. ..and it eases up. Last night. the first night that I took the Prednisone, I had pounding so bad, I was about to go to the ER again. Then I prayed, and I prayed, and was able to sleep. I don't know whether to finish this medicine or not. I have not got much sleep at all, and just want to eat everything. Help please. Any advice?
