Thank you for the query.
Your symptoms can be caused by intestines bacterial infection. Especially if you have been taking antibiotics for sinus infection
. Due to antibiotic use, regular intestinal bacteria are destroyed. This allows bad bacteria to colonize intestines. This can cause all mentioned by you symptoms.
If you are over the age of 50, colon cancer
should be ruled out with such symptoms as well. Due to this disease, partial bowels obstruction can appear and give symptoms mentioned by you.
Other possible reason of your symptoms is inflammatory bowels disease (Crohns disease
I suggest you to visit your doctor and have some tests done. If you are younger than 50, stool tests, stool culture tests, blood work, abdominal ultrasound
should be done at first. If you are over the age of 50, colonoscopy
should be done.
You may also discuss with your doctor Rifaximine treatment. This special antibiotic can be very helpful with chronic bowels infections. You should also start taking probiotic.
Hope this will help.
