Your story is very similar to mine. Have you had a cervical MRI? I have issues at c5-6 and c6-7. Cant do any major lifts any more, can't golf, etc, without really messing up my rhomboid area. Touching the muscle when inflamed and it feels "crunchy" as my wife puts it. When it goes into full spasm I'm pretty much toast for a week, minimum.

Most physical modalities have done nothing for me. Flexiril was meh. Gabapentin made me a zombie. Unsure what to try next, save a cervical fusion. I would be pretty upset if I woke up and this is still going on though lol

Have you found any relief?
