Over the past few months I've had some back/neck injuries I didn't get addressed. After a while I could not get comfortable sleeping with my neck tension. Over the past 4 weeks I have pain and numbness in my left arm and spread to my right arm, then mainly left arm and leg now when I sleep and sit in a chair. When I walk it mostly goes away or reduces by 80%. I have major muscle tension from stress. The right arm is fine now.

When I get massaged on my neck (the pain grew worse after I lifted something a few months ago)and the numbness is worse when I lay down or sit in a chair.

Is it ms? I didn't think MS numbness would go away after you massaged a neck or if you got up and moved around 90% would leave? Do numbness in the arms and legs go away with MS because a lot of mine does with heat and massage. Is that how you can tell the difference between MS and muscle tension? If you work on the body part and it gets better  it's not MS?
