Probably nothing bad: That doesn't sound like it is likely anything too serious but should probably be checked out anyway. There are some relatively rare neurological conditions that can result in muscle twitching without other initial symptoms. ...Read more

Have suspected ms, muscle weakness in left lower arm and hand gets worse thru the day but ok at night. Ms symptom or something else? Ms not confirmed.

Have suspected ms, muscle weakness in left lower arm and hand gets worse thru the day but ok at night. Ms symptom or something else? Ms not confirmed.

Here is an approach: First, be certain that problems in left arm are not associated with nerve compression at wrist, elbow, shoulder, or neck. An EMG study will certainly help. Secondly, mri's of both brain and spinal cord may be helpful, and spinal fluid analysis can also be needed. If your current doctors are unsure, get a second opinion at a nearby medical school. Unlikely, but maybe a myasthenic problem exists. ...Read more

Can a pinched spinal cord in the neck cause muscle weakness and astrophy on your whole arm and leg muscle. Can a pinch back spinal cause same.

Can a pinched spinal cord in the neck cause muscle weakness and astrophy on your whole arm and leg muscle.    Can a pinch back spinal cause same.

To involve the leg: there would have to be spinal cord involvement or a second lesion below the cervical level. If you develop increased tone and reflexes to go along with weakness and atrophy the problem may be further upstream (eg stroke). If the issue is "where is the lesion ?" the answer may need to come from a neurologist. That's a big part of what we do. ...Read more
