For a whole two days now, my husband has been complaining of a continuous pain on the upper right arm, and pins and needles in the thumb, middle and index fingers in his right hand. He is unable to sleep because of it. He said it feels like something deep in the muscles of his upper arm.
Dear Friend. Hi, I am Chat Doctor, I have read your query in detail, I understand your concern. It seems he has got some nerve compression causing these symptoms. I would advise you to see a doctor. He would do a clinical examination and would give you a conclusion. If inconclusive he might require MRI / X-ray off Cervical spine. At present, he might take a painkiller like Acetaminophen in moderated dose. A Hot fomentation over the neck should also help. This is my personal opinion based on details available here.  If you still have any query you may please ask me. Stay Healthy. Chat Doctor, MD
