I have an appointment with a doctor next week.But I want to know if this could be serious enough to be seen before then. It started a couple of months ago. I wake up late in the night or early in the morning with chest and back pain. It feels like something is crushing my lungs. I have to take very short careful breaths until it goes away. The pain in my back is unbelievable when taking these short breaths. If feels like my back is broken with each breath. At first it only happend once a week or so. The past week and a half it has been happening every night/early morning. And the past few days it has happend several times in the middle of the night or early morning. It hasn't happend yet during the day. It can last anywhere from 5 seconds to a couple of minutes. Then all of the sudden all of the pain will be gone. I can't take this pain much longer. It is hurting more and more each time. I just need to know if I can wait to see the doctor next week? Or is this more serious to where I need to be seen now? Thanks so much for your help.
