I have been having skin pain mostly on my upper torso front and back. It has also occurred on my upper arms and legs. I have no rash and It has been going on for 9 days. I also had a severe headache and nausea with vomiting one night right in the middle of this time
Hi, It might be a simple musculoskeletal pain.  As a first line management, you can take analgesics like Tramadol or Diclofenac for pain relief.  If symptoms persist you can consult an orthopedic and get evaluated. Hope I have answered your query. Let me know if I can assist you further.
