Hi, I have gone through your medical history carefully and understood your concerns. The burning sensation in your breast could be due to: - breast infection although no lump was detected. Physical examination and ultrasound of the breast can rule it out - as you have a personal history of open heart surgery, it could be due to possible cardiovascular issues. I believe you are having regular cardiac check up. If you have not done any check up recently, then I advise to get your heart checked now through ECG and echo cardiogram - neurological problems regarding compression of nerves coming from spinal cord to rule out by neurologist and x-ray of the spine (thoracal section) You need to run these tests first to determine the right diagnosis before running into final treatment strategies. All the best. Dr.Albana
