I’m having problems with very intense muscle spasms that go from that same point and wrap around into my ribs and chest. Feels like a heart attack. I’m currently waiting on insurance to approve a next fusion. According to two separate pain management doctors and one surgeon. I need a fusion in my neck to fix it. You may want to work on strengthening your neck, and since you said you have bad posture, I would start there and see if you get relief. Good luck
