All help is greatly appreciated.
This forum is for questions and support regarding neurology issues such as:
Alzheimer's Disease,

Autism, Brain Cancer,
Cerebral Palsy, Chronic Pain,
Epilepsy,
Fibromyalgia, Headaches, MS, Neuralgia, Neuropathy, Parkinson's Disease, RSD, Sleep Disorders,
Stroke, Traumatic Brain Injury

Hopefully my answer will be of some help to you. Without viewing the films, I doubt the doctors here could be of much help as to whether or not surgery is a good choice for you. If your shoulder is still no mobile, it would be worth it to be seen by a surgeon soon, imo.
Best of wishes from a vet of back surgery,

Thanks again.
1) does the pain get worse and worse throughout the day? Ie get worse the more you use your left arm outstretched in form of you ( eg typing) If so you likely have injured one of the nerves to the muscles that control your scapula (spinal accesory nerve, dorsal scapular nerve (DSN) or long thoracic nerve (ltn). the ltn and dsn can be injured with violent head motion as they leave the cervical spine and pass through the middle scalene muscle. (also can be injred if you broke any ribs onthe same side at the time of the injury. If so you cannot repair the nerve at this point but direct electrical muscular stimulation of the denervated muscle can be very helpful.
A very good emg/ncv study by an experiecned person can tell you if one of these nerves is injured.--most docs dont do this well as they are afraid if they put the needle too deep they will go through the muscles and get into lung
