I am sorry your mom is in pain. It hurts those that love her too. TMA is right the source of her pain could be any number of things. Sometimes that type of pain can actually originate in the neck and radiate into her shoulders and arms. It could also be she strained some muscles in the area. It could be arthritis is her neck. Any good physican can do the initial evaluation and refer her on to the proper specilaist that can do the final DX (diagnosis)and TX (treatment). I wish you and your my the best. Tuck
Or possibly a problem with the muscle.
You may want to start with an orthopedist. And they can always refer you to another specialist if they feel they need to.
I hope you and your Mom can find a god DR and get the pain taken care of.
