<human>: My back started to hurt about 3 weeks ago. Pain is located between scapulas, around my backbone. Pain is not consistent, I can feel it when I lower my shoulders down. It feels like something is pressing my backbone from sides. I also experienced some left chest pain about three weeks ago, it lasted about 2-3 weeks (I relate it with smoking).I tried some not prescription ointments for my back, but it doesnt seem to help.What could be the cause of that back pain?
<bot>: Dear patient Pain between scapula may be due to 1. Trapeziums 2. Dorsal spine origin. Have you suffered trauma? If not then I would advise X-ray of dorsal umber spine anteroposterior and lateral views to rule out bony abnormalities.  If its normal then start tab diclofenac plus thiocolchicoside combination twice a day for 5 days. Apply diclofenac gel for local effect. If report shows abnormalities take a visit to orthopedic surgeon.
