Hello & welcome to Just Answer,
Just wanted to know of a few things before we deal with your answer:
Since how long are you having this problem, & where exactly is this pain
How long back were your antibiotics stopped
Does it happen that every time you get abdominal cramps now, you feel like passing stools & how many times a day are you passing stools and gas
Have you been out camping recently and taking water from streams or rivulets
Are you using any outdated tinned stuff
Are you nauseated or having vomiting & are you febrile
Thanks for all the additional information.
Without having the benefit of a clinical examination, no, you do not have any intestinal obstruction since you are able to pass both stools and gas (flatus).
Your problem seems more like that of ‘Amoebiasis’ or ‘Giardiasis’. Maybe a stool test will tell the disease. In the developing world these two illnesses are quite common and lead to such symptoms. Intestinal worms may be an accompanying problem, but can be diagnosed easily from a stool test. Treatment remains simple, with a course of Metronidazole (or Tinidazole) with an antibiotic. Intestinal worms may be handled simultaneously if they are detected. Please do not use any Candida cleanse product.
Yes, sometimes they do cause such body pains and tiredness. However, it would be advisable for you to undergo a colonoscopy, as your present symptoms could also relate to Chrohn’s disease or diverticulitis. Please check in with your doctor.
As such, without having the benefit of a clinical examination, it is difficult to pin point at a particular reason. Theoretically there can be many more reasons, but simply put, one has to go by the probability based on the type of symptoms. More definite impression could be made out from a colonoscopy though.
