I have gone to multiple doctors and done multiple tests. No diagnosis yet. Pain on left side of chest right under left breast. Arises when seated for a long time or after a busy day. Been experiencing pain for about 2 months now. Have become sensitive to smells like perfume, room freshener etc. Have attached ct scan report if that helps.
