Why? How?

I say circulation & if so, what meds increase flow & rate for a test?

Stretching and exercise make my spasms worse. I drink alot of water and still the spasms wont go away.

Sloooooooow stretches help me. yoga, quigong Tai Chi and so forth. Gentle slow purposeful movements. Flat out exercise makes me go spastic which is not what I want. This way I get core training without the bulk and spasms.

But do any of you think circulation is a culprit?
Of course brain/nerve damage is a major reason, but circulation has to play a role.

Are you talking Nerve or blood circulation?

Blood. Oxygen is the test that I've tried.
My spasms wake me more when I fall asleep w/o putting ox concentrator on.
Smoking is bad for MS they say..why? Just reverse effects if thats true no?

Makes sense to me..

Every part of our body is effected by MS. I don't know if it's the cause or the effect?

slow stretching is better if avoiding spasm. In my case, spasm probably does get worse if circulation is impaired, as it was when I was on chemo for another disease. I had to quit the chemo (but took radiation).
For many years I've taken a small dose of non-flush niacin to open blood vessels and increase circulation that way. I take only 250 mg a day, 300 would be OK, depending on how the capsules are available. It is important to get the non-flush timed released ones or you could have a scary flush.
I don't know if magnesium and Vitamin E help blood circulation or nerve circulation, but without them I would have overwhelming spasm. This has happened to me when over night in a hospital without my supplements. It makes me scared of how my death will be, if hospitalized without these helps of spasm. Will they notice that I am in spasm and jerking all night? No one cared when I was in the hospital last time overnight. They said I'd have to wait for morning for magnesium, so I jerked all night and never slept. But if I'm there for an extended period, will anyone care? I don't think so, not here. Maybe in Seattle where I am thinking of going to an old folks home one of these days. Someone might care there. Doctors are good here, ER is good, but overnight in the hospital is a disaster.
