Jeff and Sharon were the most physically active MSers to receive stents (so far)...so it is hard to judge if the others will see this side effect. Marie...now that you're back to the elliptical, you working up a "glow"?
This reaction happened to both of them soon after the stenting procedure, and is probably not due to lesion healing, but more likely due to better circulation, oxygenation and faster perfusion time in the brain and specifically the hypothalamus.
Sweating impairment in MS has actually been studied:Sweating impairment in patients with multiple sclerosis.

Objectives - To measure sweating in patients with multiple sclerosis (MS). Materials and methods - Sweating was measured by an evaporimeter after a heating stimulus in 29 MS patients and in 15 healthy control subjects. Results - The MS patients sweated markedly less than the controls. After 10 min of heating the sweating was significantly lower in the forehead (P = 0.034), feet (right, P = 0.033; left, P = 0.037) and legs (right, P = 0.043; left, P = 0.029) of the MS patients than in those of the controls. After 15 min of heating the difference was statistically significant only in the feet (right, P = 0.043; left, P = 0.029). The Expanded Disability Status Scale score correlated inversely with sweating at 15 min of heating in the left hand (r = 0.42, P < 0.05), and in the left (r = 0.36, P < 0.05) and right foot (r = 0.37, P < 0.05). Conclusions - MS is associated with an impairment in thermoregulatory sweating which seems to be related to the disease severity.

Our results suggest that abnormal thermoregulatory sweating responses occur in multiple sclerosis. Thermal sweating is a reflex. The afferent portion of the arc consists of afferent neurones from dermal receptors and warm blood acting on thermosensitive cells in the hypothalamus. The principal centres for regulation of sweating have not yet been located but probably reside in the hypothalamus near the tem- perature centres. The descending fibres from the hypothalamus and the sympathetic outflow of the thoraco-lumbar cord constitute the efferent portion of the reflex arc.
