My mom thinks she has nerve damage in her shoulder......But has recently developed extreme muscle weakness in her left arm and tremors in her arm/hand and jaw. Her right arm is now becoming weak too. It is effecting her daily routines. I am so worried. She had a physical and her blood work came back perfect! She was referred to a neurologist but her appt. Isn't for another 3 weeks. I am worried she has some kind of nerve disorder or neurological disease. Is there anyone that can give me and advice or has anyone ever had this and if so, what was it? I am grasping at straws. I haven't been able to find anything online. Any response would be appreciated........Thank you!
