Over the last two years, I would periodically get discomfort from my left side of abdomen(under the edge of ribs, wing!?), the discomfort extands to my back. There is no pain if I apply pressure to the front but there is from the back. I would also experience continuous belching, like i would belch once every 5 seconds non-stop, the belching would stop if I lie down. Sometimes when the situation gets more serious, the whole body will feel unenergetic, and I can some times feel muscle aches across the body, and muscles near the area sometimes shakes/pulses. Sometimes constipation and diarrhea will also occur.

The discomfort will last for weeks before it disappears, and then come back again after another few weeks.
