Sometimes i get super intense pain that feels really horrible. Its like in my chest, shoulder, back and down my arm. (Its not a heart thing ive been checked) had it for years now. The pain locks my arm is so intense i just sort of pace and cry till it goes away. Feels like twisting squeezing and i cant move my arm or my body properly. It is quite short lived. I wiggle my fingers to try get moving. And after my arm feels weak for a bit and im tired. Is this what ms hug feels like or is there another name for this kind of pain? Anyone else experience this? Sometimes i can accidentally set it off by putting my own seatbelt on sometimes it just happens out of nowhere.
