Hello and welcome.
This is not the MS Expert Forum, which has been dormant for a long time now. There is no doctor currently posting there.
We on this forum are MS patients, those being tested, and others interested in the subject. We cannot provide you with any expert advice.
I do want to say, though, that if you have MS it is forever. It is highly recommended that you continue with some MS disease modifying drug. Immunosuppressants can be quite dangerous.
I hope you have a neurologist whom you see regularly. He or she can also give you medications to help with pain.
