I have the exactly the same except its on my left side, Iwent to the doctors in March about it, he gave me anti-inflamatory capsules, its still been there nagging and ive had some terrible pains ,I thought I was having heart pains,back to the doctor last week,after examining me he said I had 'COSTO CHONDRITIS' which is to do with bone cartilage he's given me pain killers now, I think he may be right because he actually knew where all the pain was and more or less told me where I hurt. hope this helps but if I were you I would still have the doctor check it out. Good luck.
