I had been routinly checked while I went to school for scholiosis. They found a slight curve in my back, but I do'nt think they were worried about it. After highschool I started to feel pain between my two shoulder blades. I have to constantly strecth my arms back during the day to feel more comfortable, but it's cracking everytime I do that. Does anyone know what could be wrong with me or what I should do. I won't have insurance for a month now. But i'm in pain all day long every day. I'm only 23 years old.
