of the intestine is a very common problem in our country. It can lead to multiple problems like persistent abdominal pain
etc. You can go for a deworming therapy (medicine and dose can be prescribed by your primary physician). You can get a stool for ova-parasite-cyst done (if not already done). Get a blood for complete hemogram done as chronic worm infestation can lead to anemia. Abdominal pain
may/may not be related to the worms. Persistent pain may warrant the need of an ultrasonography of the abdomen. Antispasmodics may help but should be taken strictly under a physician's supervision.
