I had an injury where my arm was caught under a 100 lb struggling dog. My arm was repeatedly pulled away from my body. I developed numerous symptoms that my doctors seem unable to diagnose, I’m hoping someone can offer some insight. My symptoms include facial numbness and also numbness down my arm into pointer finger and thumb. I also have pain and pins/needles feelings in neck and shoulder. I suffer from severe headaches and developed dizzy spells. Healthy up until this injury. My clavicle luxated and now grinds and pops. I did have a work-up for MS, all negative. I also have tried physical therapy, massage therapy, acupuncture, hypnosis, to no avail. Anyone have any recommendations for me? I have had MRI’s that show shoulder tear posterior and some increased signal near the divisions of my brachial plexus, doctors don’t feel these account for my injury.
