Hello Doydie,
I think that it is sort of standard to rule out other auto-immune sydromes with blood tests whenever someone presents with multiple area neuralgias and inflammation/pain.
As we have found out from others on this forum it is possible to have more than MS causing some of our challenges.
Celebrate that your physician is "on it" so that you get the most appropriate and effective care now and in the future

.
With love, Erika
