Please Could You Advise Me What Other Causes Could Cover

Please could you advise me what other causes could cover pains in the chest, symptoms are pain in the centre of my chest and back going up into the jaw line, I have had an angiography and this occurred in the process there was no change to the heartbeat. I maintain a careful diet as I have a condition call lichen plants which means my mouth is very sensitive to certain foods, could this be a factor?
