I had a bizarre occurrence of vomiting every day for approximately three months over a year before my diagnosis with Multiple Sclerosis. It became the joke that I was just a sympathetic husband since my wife was pregnant at the time, and thus I was bearing the morning sickness for her (and it was in the morning). Went to see a doctor, but everything came back normal – of course no neurological tests. Since the diagnosis I have suspected that this was related to the Multiple Sclerosis, but have never (well up until recently) seen anything about this symptom. I did find an article (still waiting on the full text: Hiccups and vomiting as initial manifestations of multiple sclerosis), but it finally confirmed what I basically already knew: the vomiting was the first Multiple Sclerosis exacerbation. I guess this makes two ultra-rare MS exacerbations: vomiting and hearing loss. I guess I didn’t want anything common about my disease.
Regardless, I finally feel redeemed that the vomiting was most likely the Multiple Sclerosis. I guess a reminder to us all: just because some site (NMSS) doesn’t list your symptom doesn’t exclude it being the MS!
