You sound like my twin. My symptoms are all worse on the left. My left shoulder blade aches as does my left bicep, forearm and even wrist. I have much more twitching on the arch of my left foot, and it often aches/burns when I'm walking on it. My left side just feels weaker (although there's no true loss of strength, just feels weird. When I'm working on the computer at my job, my left arm aches and I often see. I sinks teitching. I'm under a lot of stress right now, and also have Fibromyalgia which can cause fatigue and pain...I'm literally getting to the point where I'm just tired of worrying about it. I have strong faith, and I have been praying for peace and joy in my life again. It's not healthy for us to live in fear every day, and it's wearing my poor body down. I'm sure that you have a spinal problem (curvature, disk problem etc) that could account for the left side suffering g worse. You're in my prayers (as is everyone on this board), and I can chat if u wish to PM me. Be well! Hugs
