Leg and hand stiffness.
I, too, have had the brain MRI
for MS, an EMG (twice), full body nuclear bone <span style = 'background-color: #dae8f4'>scan</span>
, an array of blood work, and evoke potential test, sinus xray, neck xray.... so on, so on, so on.
Everything negative (good, I guess, except that I am still in pain).
If any of the others on this site figure out what they have, please let me know. I, too, am getting the "what now" from my doctors.
Good luck to all.
