What is the FAA's take on MS and getting a 3rd class medical? I currently hold PPL but have been flying as a sport pilot for quite a few years as both planes I fly fit under the LSA regs and there was no reason for me to bother with a medical. After having blurred/double vision for two weeks I saw my GP who sent me to a neurologist. An MRI and lumbar puncture later I was given a dx of MS. The blurred vision resolved with IV steroid infusions and the next steps are to get into the MS clinic and start discussing long term meds to keep things under control. Of course there has been no flying during all of this and I don't plan on flying again until I feel like everything is back to normal but now that I am starting to look into medications I am wondering what the FAA's take is on MS. Is it at all possible to get a 3rd class medical in the future or am I stuck flying light sport aircraft? There are 17 different medications for MS. Any I should specifically stay away from assuming I have options?
