I also suffer from severe shoulder and arm pain but on my right side. I can truly empathize and have the very same problem of lack of sleep and tired of feeling this way. I am currently seeing a pain doctor but have never had surgery for my condition. I work out every day-Pilates which sometimes helps a little but at least is a way to help calm myself down. You are definitely not alone and I hope that we can find a good solution to this. Take care.
