Your description of pain does not fit into any particular disease entity. Is it more on deep breathing, cough or change in posture or does it have any relation with food? do you have any other symptoms like fever, cough, phlegm, vomiting
. Do you have excessive gas formation because some times an air lock in the intestines can give this kind of painh. However, you should get a xray chest and an ultrasound
of abdomen done. In the meanwhile take a pain killer like meftal
spa and a pantoprazole
to counter any gastriris.
