I've had one migraine since I've been on treatment and multiple head aches almost daily. My doctor didn't mention migraines, but when I got my Pegasys booklet it did say that a possible side effect was migraine/head aches. I assume that the meds stay in ur body for some time once treatment is done so this may be why your pains continues?
I suffer migraines both pre and post tx. Imitrex is a life saver for me. jerry
