Thinking i have als. doctor did emg just right arm and neck and said i have nothing to worry about. no signs of als or peripheral neuropathy. ?

If you do not mind: Me asking, but why do you think you have als? It certainly must be a scary thought. If you do think you have it, get a second opinion, but know there are many objective tests, like emg's (if done correctly) that can point toward the diagnosis. I certainly hope its not als, but each person knows their body best, so keep listening and find the correct diagnosis. Best of luck!

ALS: Amyotrophic lateral sclerosis or lou gehrig's disease is a degeneration of upper and lower motor neurons. The diagnosis is made with an EMG and additional tests may include a lumbar puncture and an mr i of the brain and spinal cord. A second opinion with a neurologist will provide you some reassurance.

Depends on symptoms: Als is a disease of the upper and lower motor neurons. If you are experiencing lower motor neuron symptoms (e.g. Twitching, weakness) in the right arm but the EMG in that region is normal, it argues strongly against ALS as the underlying diagnosis. It does not exclude the possibility of upper motor neuron disease in that limb or other issues elsewhere in the body, however.
