Chest pain/pressure, years after treatment...

Does anyone out there still continue to have pain well after treatment done. I finished my 6 cycles of chemo for primary mediastinal large b cell lymphoma in May of 2006. I have been in remission since. Yet I still have chest pressure/pain of which no one can find an answer for (which is what brought me to the doctor in the first place before diagnosis). I had a recent scan, and mnay cardiac work ups done, all of which have come back clean and normal. This of course is good news, but would like to find something to help with my issue!
