I hear what you mean, about bad things happening to good people. Often, times, it feels that way, I truly get that.
Symptom treatment is usually the course, for many of those of us, with MS, as it is.
Sometimes, reading into MS, can be a mind game, in and of itself.
There's also a Chronic Pain group here, too, that many find helpful, to talk to other patients that may have some advice, and direction to give.

With or without, answers, at the moment, it's important to have those symptoms treated. Sometimes, as patients, when we focus on the potential illnesses, instead of the immediate symptoms, the doctors cannot help. And sometimes, if the doctors aren't listening and taking your pain seriously, then it's time for a second or even a third opinion.
