More questions for my Doc.

I started out with my Doc wanting me to get 5 days in a week each month . After 4 days, I could not move because of such a bad headache. He decided to break up the sessions to get rid of the headaches and put me on tylenol and benadryl to start. I am already taking pain medicine on a regular basis so I hate to take more but I will ask about going once a week. Anything is worth a try. I would like to get my symptoms under control.
Thanks for your help.
