May be u r sitting for long hours / postural I'm balance is there.      Soft tissue injury or vertebral misalignment or any lumbar problems u might be having.. Undergo the MRI frst. Get the clear picture once the issue is known , physiotherapist can cure you for 💯%

See first of all if you have over weight so plz reduce because mostly back pain due to fat people.and if everything is ok so do regular excersize and some hot water apply on back

If the pain is still not better with other remedies , you need an evaluation by a Spine expert ( Physio or an orthopaedic) and rule out shoulder or cervical cause . Any mechanical problem with shoulder/neck can be identified by an Mckenzie Certified physiotherapist. You can search for one online in your area .

LETS FIRST GO WITH MRI SCAN OF UPPER SPINE AND MEET PHYSIOTHERAPIST FOR BETTER ASSESSMENT .............

Take a rest and ice pack on swollen ares. Visit to the physiotherapist and take a proper treatment. Ask for home exercises, correct posture and ergonomics.  

As the pain is persistent, that means there must be some underlying pathology that needs to be diagnosed and due to that the swelling has developed. You can have a proper assessment and treatment through an experienced Physiotherapist. Thanks

Rest must and physiotherapy treatment will help you

Use icing over the swollen area. Visit to the Physiotherapist to get relief from pain. Improve posture while work so follow ergonomics. Avoid forward bending n weight lifting

Chiropractic adjustment will help. Hot& cold Pack. Gentle shoulder stretching.

Hi.. Back pain is much obvious with continuous sitting in office.. Start with hot n cold thrapy-2mins ice followed by 2mins hot water/hot bag... till swelling subsides.. then continue with hot water formantation.. apply myolaxin ointment.. sleep on your stomach and lift your neck and shoulders-this will give u good stretch on your back.. At office avoid being in one position for long.. take proper pillow from neck to back on your office chair for sitting.. eat lots of fruits-will help u for healing.. Drink 4-5lits of water.. stay hydrated.. that's important. Thank u
