dear user about your question i would like to tell you that these symptoms you mentioned refer mainly to have gastritis that lead to burning pain you feel in stomach..........your feeling of nipple pain should not make you worry as it is common problem with the period of women as hormonal changes occur and cause nipple pain or breast pain so you need not to do any thing with that.....about gastritis you have i want to tell you that heavy meals or fatty food always cause these symptoms as there is maldigestion of heavy meals leads to increase gastric acidity and gastric burn sensation ....about management of that you should avoid stress and anxiety as it increase the gastric acidity....... ...heavy meals or fatty food that may get your symptoms worse ........you can take rantidine as it has effect antagonist to gastric acid and also you can take omebrazole which decrease synthesis of gastric acid .......also drinking very hot drinks will increase acidity of your stomach .......smoking and spicy foods and coffee drinking and tea drinking has main role in gastric burn you feel...............wish you healthy life
