Nerve damage: If you have unilateral muscle weakness and atrophy there has to be an injury or impingement of the nerve which innervates that part of your leg. A demyelinating process such as MS may also lead to muscle atrophy and weakness unilaterally. Other causes may be trauma to that muscle, prolonged immobilization in a cast, or not weight bearing on the leg can lead to loss of strength and muscle mass. ...Read more

Can nerve entrapment cause weight loss, muscle wasting and muscle weakness.

Can nerve entrapment cause weight loss,  muscle wasting and muscle weakness.

No and Yes: Motor nerve entrapment can definitely cause muscle wasting & weakness - but only of a particular muscle or muscle group innervated by that nerve. It's unlikely to cause weight loss except if you lose a large amount of muscle mass.If generalized weight loss &/or generalized muscle weakness is occurring, you need a proper medical evaluation to determine cause; it's unlikely to be nerve entrapment. ...Read more

Raising arm unconsciously during sleep causes this space to close by a few millimeters, pinching main nerve ; artery to arm. Ulnar parasthesias (crawly tingling feelings) occur in pinky side of hand.

I have some facial muscle weakness. Brain MRI about a year ago showed nothing.  Was told it was anxiety. Could that be the only cause?  I fear als.

Doubt ALS: Weak facial muscles are associated with a few hereditary muscle diseases (e.g., fsh), but can be due to problems with cranial nerves, such as facial or trigeminal, and problems outside cranial cavity may not be seen on standard brain mri. Very unlikely that you have als, but if you need more information, a facial nerve EMG might be of some value. ...Read more
