My mother is 86 yrs old. She is experiencing pain in her left arm in her upper muscle. She also has experienced tingle feelings in her hand. Been to dr and he thinks it could be carpal tunnel for the hand and is not sure about the muscle pain. Pain pills stop the pain briefly and she is ok when she does not move the arm. Our biggest problem is that this is the only arm she can use as she had polio in her right arm years ago.
