For about the past year or more i've been having chest pains right around my heart to the center of my chest area (Hard to pinpoint.) I went to see the doctor about it a little while ago and he did a CT, EKG and Blood work but all those came back clean as far as my heart was concerned. He did say i had a mass of scar tissue in my lung, he doesn't know what from and neither do i. I'm 20 years old, and i don't smoke or do drugs. His best guess was that it was from a high fever when i was a child. The chest pains are still there and i don't know what could be causing them, but it doesn't feel like it's my lungs. It's a sharp stabbing pain that isn't constant and comes and goes whenever it seems to please. I've tried to link it to eating habits, caffeine intake, exercise, water intake, heat...pretty much anything i can think of. It always happens in the same area and it lasts anywhere between 30 seconds and 10 minutes.
Also, recently i've had a problem with being dizzy, mostly just after i lay down or if i ever tilt my head back. I've tried to see if exercise or caffeine causes my symptoms but i've done some pretty hard workouts and have had moderate amounts of caffeine but the symptoms seem completely random. Does anyone have any ideas of what i could have the doctor look into? I'm not in particularly good shape but I have been losing weight and doing more exercise...nothing i can do seems to help with the random occurences or the amount of pain or dizzyness that accompanies them.
Any help would be greatly appreciated!
