It’s probably not MS. Try to calm down a little bit, just focus on breathing in and out for a few minutes.
Are you a side sleeper? I have hand problems from sleeping on my side, I sleep on my back only now then the hand problem heals. Hot pack that you heat up in the microwave, apply that 4 times a day. Not too hot just hot enough. I’ve just healed a numb thigh that way. I would wake up and my whole thigh was totally numb. I would do the heat pack on the whole shoulder and all the way down. As hand issues generally are from the shoulder area or arm.
The heat will increase circulation. Buy a herbal bottle of pills thats for increased circulation. I bought a veins clear one as those herbs really got my circulation working properly.
Don’t stress. You are ok.
