<s>[INST] I am having a lot of pain from my neck down my shoulder & left arm with tingling in my fingers. The pain is so bad I can not hardly use that arm to do anything. I do use a cane to walk with on that arm, so I m not sure if that is causing it problem or what? [/INST] Welcome to Chat Doctor I have gone through your query and understand your concern. There are basically two causes of such pain. One is a cervical spondylosis and another is cervical disc prolapse. It requires clinical examination, your age, x-ray and MRI to make the diagnosis. Basic treatment of it is rest to neck, Mecobalamin and analgesic such as ibuprofen for pain relief. You can discuss with your doctor about it. Hope your query get answered.
