First of all,let me just say that you are an amazing person just because you have not given up. You could go to bed and feel sorry for yourself, but you have chosen to do something about your pain. I am sorry that you have to go through so much pain. I know there are many that can relate to you. I know I can on a smaller scale. Quality of life is important. After you get that shoulder looked at you may want to consider something my chiropractor suggested to me. I started going to an aqua arthritis class at the local fitness center. Wow, Did that help my back problems. Once I got over the "going to the pool" obstacle (I once almost drowned and have a fear of water) I discovered relief from pain and a huge improvement in quality of life. Just a suggestion. Hope and pray you will find relief.
