to you both, savannah and bodhi brainMD!
Savannah, I have extreme heat intolerance, along with my neuropathy. (In all fairness, I must mention my doctor is also in the midst of ruling out MS again.) I am "in trouble" if the ambient air temp is above 65 or so, and especially if it is humid! As soon as I cool off, things are fine.
When I was working with a physical therapist, trying to build more enduarance, we'd place ice packs on my spine immediately after I was done exercising, in order to try to cool my body core temp as rapidly as possible.
Many have given great links and information!
