I have had a pain on the right side of my chest for over a year had tests done but nothing found. Hard of breathing, feels like something is grabbing me tight and stopping me from breathing. It really hurts and sometimes burns. Last few times i have been to the toilet for a number 2, there has been blood in it and always getting bad heads, dont no if it is connected? I have also had a bad back since i was 14, i am now 22. Have been taking Ibroprofen since i was 14, stopped taking them for the last few month. Any idea?
