I wretched my back two days ago and since have pain in one spot between my shoulder blades when i swallow/burp. getting better , but is this nerve ?

Intrascapular pain: Can be reflux try ranitidine, muscle strain(erector spinae-behind esophagus) that were irritated during trauma and by swallowing. Osteophytes can impinge on the esophagus, unusual at a young age, Osteophytes develop slowly but position may have shifted . A compression fracture would be rare . f/u/ w/ doc consider motrin if not allergic muscel relaxants
