My husband started having right shoulder pain and couldn't lift his arm in a certain way. He went to our ortho doctor and got a steriod injection into the muscle? or joint not sure which, and then told to have physical therapy 3 times a week for couple weeks and see if that helped. He thought he had tendonitis in his shoulder.
He now has had about 3 therapy sessions. At the first one, the P.T. felt a knot underneath his arm, high up and said for the doctor to check it that it shouldn't be there and may need an MRI to see about it. Well, my husband came on down to where I work (for a doctor) and he remembered an old injury to that arm and said he had torn a tendon or something loose and that was the end of it instead of a knot.
So he goes on to his therapy and they use a machine on him that stimulates the muscle....electrical current type thing not sure what it is called. Now he is having hard very noticeable twitching in his upper arm. Today he said it had moved down below the elbow into the hand and was pain. Almost like it followed a nerve or tendon into the hand. Said it happened several times today. Also, is having some cramping in the backs of his legs too lately.
I know low potassium can cause cramping in muscles but not this jerking/twitching he is having.....or at least never had a patient tell me that. Husband is using a lot of sugar substitue in his tea which he drinks a lot of and wondered if that could be it. Doctors office closed tomorrow but any ideas out here???
