pain left breast cough 103 fever cannot sleep on side?
com seems you are having a chest infection with or without pleuritis. your pain is either due to pleuritis or a muscle strain in your left upper chest or back due to coughing. i recommend using hot packs on your pain area. if it does not help then you need to see a pulmonologist. if your cough is productive you need to do a culture of sputum.
