my upper right arm has been sore for about a week, the muscle was extremely painful to move..like it was stretching. al of the sudden the area started to swell up and began bruising yesterday. i didn t injure myself, so i have no idea what happened to cause this pain/swelling/bruising
Hello, It could be a sprain. As of now, you can use analgesics/anti-inflammatory combination like diclofenac/serratiopeptidase for symptomatic relief.  If symptoms persist better to consult an orthopedic and plan for MRI scan. Hope I have answered your query. Let me know if I can assist you further.
