About 9 months ago i got really bad pain in ribs on right side, felt like I had bruised ribs but I hadn't done anything to get that, I just woke up with the pain an it lasted for about 3 days. This pain came back again a few weeks later. That pain the next time then changed to just sharp darting pains with a constant discomfort pain just across the bottom of the rib cage coming in from the side and may just come at work during the day and last for few hours, generally sitting back will ease it while I'm sitting but driving drives it mad. It will go though if I go for a run or train. The pain kind of feels like something sticking in it or ribs going on top of each other, might get shortness of breath sometimes and if I take deep breath can feel it at the bottom of the cage or I can get sharp pains in chest. It could go away for few weeks but comes back an last few days, it seems have gotten worse though and lasting longer. At the bottom of my rib cage one spot is tender to press on. I know if I go to doctor pain won't be there and he will just tell me there's nothing wrong, does anyone have an idea what it might be and should I bother going to doctor?
