pain in my left breast accompanied by a burning sensation

Hello,
Welcome to ehealthforum,
It is difficult to comment on the cause for breast pain and burning that you describe without examining you. You should consider visiting your doctor/gynecologist at the earliest for further evaluation (and investigations as indicated) to look for the underlying cause. Treatment as appropriate would be started to help you based on examination findings and investigations results. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
