Hi there. I'm 34 with no other health problems. I was diagnosed with a 4mm herniation last year. Oddly, it was an accident that it was found on an MRI for what was thought to be a mini-stroke (it wasn't, just a horrific migraine). What kills me is that several docs (including the neurosurgeon who diagnosed the Arnold-Chiari) said it would not have accounted for all of my symptoms. I have suffered from balance issues, mild memory/concentration problems, drastic changes in blood pressure from simple movement, occasional shakes, weekly migraines, neck/shoulder spasms... none life altering, but do sometimes zap my energy to take care of myself and family.
Looking for others' experiences...
Take care!
