Your form of MS is most likely RR(Recurring/remitting)which will come and go on its own.
Some folks even report symptoms disappearing completely never to return.
There are too many unknowns about MS, the cause hasnt even been determined.
I have it myself. Going on over 25 years.
For me, there was a period when drinking a bottle of cold water would make all my walking issues disappear.
Thats no longer the case.
Unfortunately when it comes to MS, only time will tell.
