Many NTOS patients develop chronic pain. Even after surgery scarring and myofacial trigger points develop/remain. In some cases, fibromyalgia or a fibro like hypersensivity (chronic pain syndrome) can develop. For me, I developed rotator cuff bursitis/tendinitis which worsened post surgically.

I recommend finding a pain management doc who is also a neurologist. Also consider seeing an orthopedic shoulder specialist.

For me, the best treatment for scarring and trigger points has been medical massage therapy (not spa). Trigger point and nerve block injections may also be indicated. My rotator cuff tendinitis is managed with cortisone injections and scapular postural correction.
