I know what you're talking about, B2Y...I have fibro, osteoarthritis and IBS along with our friend MS...the fibro, IMHO, is a part of the MS...but the pain is different than the spasticity, at least for me. The fatigue feels the same tho...
the IBS can be triggered by stress for me, as well as MS sxs...but I have read that IBS is under the sxs of MS too.
I do wonder about the arthritis...I know that both my dad and mom had it, so I drew the lucky short straw on that one...
How about depression? Ugh, I know it's associated as a sxs of MS, but it's horrible enough on it's own...

I never seem to blame my good mood on MS...although that could be IEED... another sxs of MS...
