Hello. lately i've seen a change on my stomach , the left side of stomach is bigger then the right side. it doesnt bother me at day but at night its like being full of air. sometimes makes some noise and is annoying. Also sometimes (mostly when i go to sleep) it gives me a very big inner temperature and it seems like its being depleted to brain owerheat and cause me like feeling weak. any idea what it might be? thank you.
