Hello and thanks for the query.
Most cases of upper back pain involve the ligaments or muscles that attach to the vertebrae. Usually, this can be due to a number of different factors including poor posture, overuse, repetitive lifting of heavy objects, or a related injury. Also sudden, awkward movement can also cause upper back pain, such as when twisting or bending. The main symptom of upper back pain is usually pain that is localized to the upper or middle portion of the back.
 When taking a beep breath, coughing, or sneezing, pain might also be felt in the back. You might also feel discomfort when the area is touched. Muscle spasms might signal the early stages of upper back pain. In many cases, intermittent ice packs or heat pads might help to reduce pain that might be associated with soreness. This generally helps to reduce pain and helps to loosen muscles that might have become stiff. Over the counter anti-inflammatory and muscle relaxant  medications might also be helpful.
Keep your sugar under control
Take proper calcium and VIT D.
Take some VIT B12 orally or in the form of injections.
Do these conservative treatment And wait for two weeks to see the response.
I have a feeling,you should be alright.
However if you are still not alright or may be even worse after two weeks,then you must consult an orthopedic  for a CT or MRI of the thorax to see the exact cause.
I hope to have answered your query.
Please do write back in case of any doubt or any further query.
Best of luck.

Hello
If the pain is because of some lung involvement then you should have
Cough,fever,may be breathlessness etc but you you have not mentioned any of these symptoms and also you are not getting any benefit of antibiotics which you should have got had it been some lung infection.
Given the information by you and not having the facility of examining you,still i feel that probably you don't have any lung invovement.
Thanks
