Unexplained upper back pain

I get this upper back pain but I went to a rheumatologist, chose them myself and they diagnosed fibromyalgia.Always bothers me when drying dishes or spending two hours in the kitchen, told they were tight, but there are risks with neck massage so just put up with it.However the rheumatologist said the best antidote was exercise and I don't take pills due to side-effects.

@catlady87 do you sit in the same position with your computer, tablet, cell phone, etc? I’ve found that I usually sit in my same easy chair with my arms in the same position and the result is pain across my shoulder blades. I have a compensating scoliosis in that area so my left side is weaker than the right. So one side pulls on my thoracic spine. I also have OA of my entire spine as well.

catlady87, mine sounds exactly like yours. I have slight scoliosis to the left which gives me rotation ( a different plane) to the right. I've been reading that scoliosis that begins in the lumbar region results in upper body rotation in the opposite direction. This rotation in the spine raises the connecting rib, just slightly. so that the rib rubs uncomfortably against the muscle under the shoulder blade. My scoliosis has it's highest degree under the shoulder blade. The counter rotation is at T2 and T3. The chiropractor can reposition the vertebra which gives me instant relief which I lose after sitting for long, unless I use a pool noodle vertically behind the aching side which would be the opposite of the scoliosis rotation.
None of this is evident in a supine MRI.
You might see a chiropractor. They are easy to get in to see. You don't have to have an adjustment, but they can tell you about the mechanics of your back by feeling your bones.
The discomfort is annoying.

Try MFR deep myofascial tissue release there’s a section on it at the Mayo Clinic forum online. If you are an older person that may be from repetitive motion activities like working brought on by your profession. As we get older, our muscle groups weekend and they attach to each other And they pull on ligaments and bones, causing lots of pains deep my facial tissue release will tell you if that’s where your solution lies. Which I think it is because it sounds like it from the areas you explain and how they are involved. Try a couple different therapist because they each work differently And if it has been brought on by poor posture and a lifetime of work, you’re going to have to do this on an ongoing basis to age better. Unfortunately, I was born very round shoulder, and I was also an artist working very long hours and still continue to abuse my body. I also have degenerative disc disease so I’ve also had multiple surgeries that involve my spine and bones. However, I continue to struggle with placing a demand on my musculature because I want to continue to do art and work at 68. So for me a myofascial release therapist is going to be something I have to figure in probably for the rest of my life as well as a good exercise routine as well as cutting back on hours. I go twice a month and I could sit for nine months now and I can really feel over nine months the muscles breaking down as groups. However, when I work long hours still doing Art they’ll clump back together because that’s a lifetime habit.. There’s a saying “you play you pay“. It should’ve been “you work, you wear“
