@ksdm, I totally understand about ‘this is one muscle and it’s a killer’. Mine is when I ‘wash windows, that reaching out forward and circular motion or sitting at my dining room table and writing a letter/card, the lifting my elbow up shoulder. Like you I’ve had all the x-rays and MRIs. As far as acupuncture goes, I’ve been a couple of years working with the Dr. it is not a go once or twice etc and then you are fixed. I’m thinking it is my weak spot and I have to deal with this. I’m praying that the nerves that were cut will repair ‘eventually’. Acupuncture has been a huge improvement. When I had an episode (that’s what I call the major pain & some spasms) - I would be laid up literally for 5-7 days. Now is it 2-3 and mostly pain not so much spasms.
If I may ask , what started your spasms? Does exercise help at all to loosen muscle? I’m just shy of 72, but like you, in good health other than this muscle/thoracic/Serratus anterior muscle issue. Blessings to you. Keep in touch and I’ll pop back in to check on ya. ❤️
P. S. That chiropractor sounds scary. I would have left too. Stay strong
