Hello all , I have been reading the posts on the sight as I was diagnosed with RCVS as I said in 2007. I was sent to the mayo clinic in 2008 when I had one more thunderclap headache. Was frustrating because they never have been able to tell me cause. Some docs at mayo say I had a small stroke, yet my dr at the headache clinic I go to say no, live with migraines, but not other residual effects from event. I just asked my new doc at headache clinic I go to if it could happen again . He says not saying it couldn't, as with age vessels are narrowing. Hope it never does as pain of thunderclap is like no other pain I have ever felt.
