Nerve Twitching In Arm Muscle
Fasiculations: Fasiculations may be a benign finding but when localized to only one part of your body it might be a sign of nerve damage; you say that you are having arm and neck pain which raises the possibility that you might have irritation of one of cervical (neck) nerve roots. If present, it would also explain why you see Fasiculations. If your signs/symptoms worsen/ persists consider a visit to your MD ...Read more
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
What can cause muscle tension like muscles in lower back involuntarily flexing, clenching jaw, muscle pain in arm and neck? Also tingling face and arm
Yes- it is possible: It depends on what nerves and what muscles. If you were to say however the twitching is all over, it may not be fair to say it came from the back. Do you know if you have pinched nerves in the back, or do you have twitching only? Where is the twitching, and how much is there? Maybe start by answering those last two questions. Good luck! ...Read more

What would cause tension in left shoulder blade, muscle spasms in shoulder blade, chest, and in upper outside of arm (not bicep)?
What could cause numbness in left pinky/ring fingers and joints, neck/shoulder tenseness, crippling left side sciatic nerve pain, left eye twitch?
Muscle vs. nerve: You may have strained a muscle, or the muscle is inflamed from overuse or an inflammatory disorder (though these typically cause more diffuse muscle pain). Numbness is usually due to a (peripheral) nerve problem in the arm itself or at the level of your neck. You would need a neurological examination to determine what testing (if any) is needed further. ...Read more
What causes abnormal needle EMG in Latissimus dorsi muscles (on the sides- no electrical activity), upper arms/body weakness and scapular winging?
Yes: There are many causes for this...Most common is of a nerve being pinched in the neck that can lead to spasming of the shoulder region with numbness of the hand. This is known as a cervical radiculopathy. There are other possibilities including an injury to the brachial plexus or carpal tunnel syndrome. You should see either a physiatrist or neurologist for a full exam. ...Read moreSee 2 more doctor answers
Muscle weakness x 1: weakness on one side, in one muscle group, could be due to injury or something called radiculopathy. The latter is a pinched nerve root in the lower back.

Can a pinch nerve cause tingling numbness in arms hands fingers and toes. I have extreme muscle. Tension in neck shoulders and sharp back pains spasm?
It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more
