New Symptoms

I have been getting migraines for about 15 years now. Some weeks I get them on a daily basis due
to my stress level. I've had years of tests, but really nothing has been diagnosed. I am currently
using Imitrex and I had the way it makes me feel, so I use it only when an absolute necessary, or
when I am at work.

I had two this week - one Monday and one Friday. Both Saturday and Sunday,
I woke up feeling like I was drinking all night. The right side of my head (temple area) has been throbbing
so bad that I almost had my boyfriend take me to the emergency room. I have had all of the normal symptoms,
but never this unbearable throb. It worsens when I stand up and it worsens when I sit. I'm ALWYAS able to sleep,
but the pain is so bad that I can't even close my eyes. Has anybody had this before in association with their
migraine? Please advise. I'm a little freaked out about a new symptom.

Thanks!
