Hi, ive lately been having problems with my chest and back. Around 5 days ago i went to the doctor because i was having a stabbing pinching feeling in my upper spine when i swallowed and breathed. he said to wait a week and come back, and today i noticed there was blood coming out when i went to bathroom, and it was in my stool, and just a few minutes ago, i get a sharp pain throughout my whole chest and ribcage area when i bend and breathe deeply. please help.
