2penelope, What works for me to break days of migraines is a very low dose taper of
prednisone. I usually do 30 mg, 30 mg, 20 mg & then 10 mg. It has worked wonderfully for
me to break the cycle of days of migraines.

Migraines are caused by inflammation and Prednisone reduces inflammation. With years of
migraines, this is the only thing that I have found that will work.

Ask your Primary doctor if he will prescribe a short taper of prednisone.

Blessings & Prayers....
