Sometimes I suddenly feel a pain on the side of the body ...

Hi! Sometimes suddenly or even when I walk I feel a pain on the side of the body height of the last rib bone, a few stitches (not on the bone) and I feel a lot of sickness sometimes for something I eat. Can I have something serious?
Expert answer:

It may even be something serious, but the most common are the less serious illnesses. The pain can be musculoskeletal pain and nausea can be a gastritis or gallbladder or liver problem. Go to a doctor, for the correct diagnosis and to do the treatment.
