a major difficulty in walking (this symtom seemed to develope between one day and the next) that went for at least a month drove me to finally see a doctor.
my primary finally sent me to a neurologist.
this neurologist sent me for tests and physical therapy , therapy(exercise by any other name) was a waste of time for me also.
it took an extended stay in the hospital , for appendicitus , to get tested and diagnosed by a neurological team with some experience .
i am now on a regimen that works well for me.
hopefully you will be fortunate enough to get the right help before you get to the point i did.good luck to you.
