Hi , I have complex Regional Pain Syndrome in my right arm , and I was recently hospitalized because the doctors thought it was spreading through my chest, making it hard for me to breathe , but now i can barely walk because my legs feel like they are falling asleep and kind of numb but they are not. Now I have pain throughout my stomach, ribs, around my hips and where my neck meets my shoulders. It kind of feels like a very bad bruise, but no bruising is present. What might be wrong ?
