Stay hydrated and make sure your vitamin D & calcium levels are good. I get all kinds of spasms when I'm dehydrated.

Ms Cauthon I hope your neurologist told you or others with ms could explain ms hugs: different for some. Mine usually start because I'm dehydrated. My ribs and sides squeeze making me breathless & tired. Sometimes accompanied with dizziness & lightheadedness. All I could do is be very still & breathe deeply. I don't take more medicine for this but drink hot peppermint tea. Usually calms down anxiety.

What are the symptoms of the MS hug? I get a severe cramp in my back, travels up to the neck and jaw and is very hard to breathe. Feels like a heart attack, but went to cardiologist and everything is fine with the heart. No one seems to know what this is. It is quite frightening.

Ms Weigand says truthfully about the neurologist telling you If your back spasms are ms-related.
I have lesions up & down my brain stem & back, which there is considerable pain all the time. I was on baclofen nearly ten years when Dr replaced the drug with neurontin (gabapentin). When pain became intolerable, had nsaids to calm it. Now have tegretol with it because my legs will sometimes be inflamed to the point it's hard to move. Cannot take nsaids now. Physical therapy exercises do help.
Hope you find my experience helpful for you.

I get tingling in my left shoulder blade area, only a larger area. Like bumble bees buzzing under my skin. It can last several hours at a time for over 2 months now. Not sure if it's an MS thing or due to spinal stenosis. Differentiating between the two can sometimes be frustrating.
