Rhomboid nerve pain

I have a complex problem and I can’t get a concrete diagnosis. It’s a long history but I was a healthy woman doing a push up in an aerobics class in the year 2000 when I felt a mildly painful muscle pull in my right upper back between my spine and scapula. Almost immediately I went into a severe spasm involving my upper back, torso, chest wall and R face. My vision was obscured on the right. I had no idea what was happening. The spasm lasted 48-72 hours and after it was done I was left with R chest wall and R back pain and r face pain . After years of trying to find an answer and getting a wrong diagnosis and treatments I gave up and the pain eventually settled down in the
same spots but became like chronic low level musculoskeletal pain until last year. When all of a sudden I developed electric shocks and shooting pain from the site to both posterior shoulders and the inside on my arm and burning upper back pain. This was now bilateral but mainly on the right. I had to be put on gabapentin. I found a physiatrist who thought it was my cervical spine. Never had back or neck pain or arm pain all those years nor any medical testing. MRI showed c5-6 ddd with bilateral moderate foramina stenosis. Went through multiple bouts of PT and then injections. Suddenly last June I had shooting pain in my neck down the front of my right arm and under my right axilla with a muscle spasm occurring behind my right scap for 1.5 days. It was painless twitch. I started to get pins and needles on cervical extension and a “buzzing” sensation r neck. So I ended up having a c5-6 disc replacement. It went well. The symptoms of the pins and needles and buzzing went away but my chronic chest wall and back pain persisted. I was elated however thinking that after all these years I got a diagnosis. However in April of this year I went back into sudden nerve pain at the same site ( right back over rhomboid major) and my trapezius muscle spasms, radiating pain to chest wall, midback spasms on the right side over the ribs running into the r torso. At first I was told this may be nerve recovery but I kept getting shooting pains especially under my right axilla. I don’t know how to get a diagnosis. I know that my serratus muscle is weak and that I have Notalgia Paresthetica which gets worse when I have spasmed in the past year and 1/2. Any ideas what I should do I would appreciate
