<s>[INST] I have been having pain in my left arm for about 3 weeks and it gets worse at night.  I cannot sleep because the pain is so bad. I put ice on my arm and get some relief but it still hurts. I had shoulder surgery for frozen shoulder in October but my orthopedic doctor doesnt think that is causing all my pain.My pain starts just below my shoulder and goes all the way to my wrist. Pain meds so not stop the pain. [/INST] In my opinion I think your past surgery in October decreased the pain of your frozen shoulder but still you have some neuropathic pain due to neurovascular compression of your nerves. I suggest you ask your neurosurgeon for some imaging on your cervical spine like CT, MRI, x-rays for proper diagnosis. For now, I recommend some physiotherapy withe topical gel massaging or even yoga is very effective. Advil, muscle relaxants, Acetaminophen will be effective Hope the above information helps you. Any further clarifications feel free to ask. </s>
