I've had the same back pain for well over 2 years now. It started out as a burning/stabbing sensation in the fleshy part between my spine and my shoulder blade and it tends to seize up and I have to physically loosen it up. I would experienced in around once a week. Times which I could really pinpoint getting the back pain were when I was tense, for example, I would suffer during driving lessons.
Around 10 months ago I went to the doctors with it and he sent me to a physiotherapist, saying that I just needed to strengthen the muscles. I visited this physiotherapist 4 or 5 times and did exercise in between however I stopped as I wasn't noticing a change whatsoever. I have also had a number of sports massages on it where the masseuse has said there is definitely something is wrong and can tell where I will be in pain when he massages a certain spot but it hasn't helped my problem.
In the past 4 months I have joined a gym and I have really been focusing on strengthening this part of my body but with much dismay it has gotten worse and I have been experiencing the pain non-stop and even on days where I haven't got the burning/stabbing sensation it feels bruised and too tender to touch it. It's inhibiting sleep and I'm in constant pain.
I have made a doctors appointment for the 10th of December and I really need some pointers on what could be wrong so that I can tell the doctor myself what could be the problem and I hopefully won't get palmed off again.
Also, I'm not sure if it's of any significance but when I roll my left (the painful one) shoulder or just move it, it crunches and clicks which I do not get with the right.
Anything you think could be the source of this problem or anyone who can relate please let me know!
