[|Human|] My husband has been experiencing pain and weakness in his left arm and also numbness/ tingling in his left hand . He went to a specialist last week and he thought it to be a pinched nerve due to the disk in his neck . He sent him for an MRI and called back a few days later saying that the MRI showed a suspicious spot and they wanted to do another test at the hospital next week. My husband said the nurse said something about sonogram/ultrasound on the phone. He has been researching on the Internet and has convinced himself that it may be ALS and now I m worried as well! Do you think it could be this? Thanks for your time!
[|AI|]  Hello and thanks for the query ALS is a motor neuron disease and usually diagnosed by clinical symptoms. On other investigations is a definite test for diagnosis. MRI scan came back normal in patient with ALS. The problem you are facing is most likely to be PIED of the cervical spine as your doctor has in his mind. Weakness, numbness and tingling are present in this disease. So don't worry and go through the investigation and then get to a decision. There might be some technical problem that result in repeat scan. Best Wishes
