Hi, I'm 16 years old. Over the last week it has been hell for me. Everytime I breathe in I get a sharp stabbing pain in my left lung so I went to the hospital as my gp was closed. They said it could just be costochondriitis. I was prescribed 15mg of codeine(1 weeks worth) which helped releve it but it was still there. A few days later I found a boney lump which I can't tell if it's on my last rib on the left side of my rib cage about 4 inches from where I get the pain when I breathe in. So I went back and I was told they can't point a finger at what it is as I had only found it a few hours prior to this and that if it's still there within a week I had to ring my gp to get a scan. 2 days later I started getting yellow/brown bruises on my left leg below the knee. So I have been back in touch with my gp and I have to get blood tests done and he said he needs to do some other things which he didn't say also I never got told a referral date for my scan or nothing just be to at the doctors 9:30 tomorrow morning. I would like to know if anyone else has experienced this sort of thing and if I'm just making my self paranoid or not?
