I have experienced a sinking and a bubbling feeling in my lower-stomach
Hi Aftab. Thanks for your query. The feeling of sinking and bubbling in the lower stomach can be due to an intestinal infection of mild form. I would advise you to consult a local Doctor to get you a 5-day course of an antibiotic and metronidazole with probiotics. This may solve your problem, and you may not have to do anything more. IF there is no relief you can go for the investigations of the blood, urine and stool. As also ultrasonography of the whole abdomen and endoscopies if required.
