I have what was diagnosed as cluster migraines. I have been fortunate to have only 2 bouts in the past few years. They are not full-blown but the first one lasted 6 weeks.
I thought I was going to lose it. Nothing I took helped because I was already into it a week or so before they ran test and narrowed it down. I just took pain meds to keep it to a low roar and then I guess it ran its course and as quick as it came, it left.
I only had one more episode that didn't last as long, I get frequent headaches but nothing I can't handle.
Hope this is helpful in some way. There is nothing more irritating than a constant headache.............well I guess there is but it is up there in the list of chronic pain.
Good luck to you,
Judy
