My son is 8 yrs old now. In April , last yr, it started with a severe pain in his upper abdomen( just like gastric pain ).USG was done but report is normal. The pain is like a cramp.It starts all of a sudden, remains for a few seconds and goes away,,,,, Doctor said there is nothing to worry. It is due to worms.Is there any way out to get rid of this frequent cramp which starts just after 2 months from giving worms medicine .? The action of med doesn’t remain till 3 months, just after 2 months the problem starts.
