I Had Monthly Migraines From Age 10 To Long Into

I had monthly migraines from age 10 to long into my 70's. Also have fibromyalgia. Periodically I have a migraine and what I thought was a fibro. breakthrough (I am on Gabapentin 3100 m daily) But now (and I am 81) my doctor told me that there is something called full or whole body migraine. The pain is intense, feels as if I am on "the rack" or have been run over by a truck or coming down with worst flu ever. If I take an Amerge for the migraine it does seem to ease up a bit on the body pain. Your thoughts?
