<s>[INST] I have pain and sore muscles in my upper left arm. No chest pressure or pain. Arm, muscle pain started out about 2 days ago, slight arm muscle pain and has increased so that it s hard to lift my left arm. Taking advil helps, but it s pretty sore currently. [/INST] Hi, It may be a simple musculoskeletal pain. As of now, you can take analgesics like Acetaminophen or Tramadol for pain relief. If symptoms persist, you can consult an orthopedician and get evaluated. Hope I have answered your query. Let me know if I can assist you further.
