<human>: I had sudden pain left side, on my midback. . . not on the spine. It was like a popping sensation. Pain went around my left side . . then next day I noticed a dark bruise the size of a half dollar on my left side adjacent to my belly button. Any thoughts?
<bot>: Hello, As the bruise on the belly is not connected to the upper back pain. This may be some other thing and needs an abdominal examination on a clinical basis. The pain in the upper back one side will be related to Trapezius and inter-scapular muscle spasm. Doing hot water fermentation, gentle kneading massage, myofascial release, strengthening exercises should help ease the pain. Hope I have answered your query. Let me know if I can assist you further.
