<s>[INST] my 6 yr old son started complaining about stomach pain near or above the belly button the other day (Saturday). Sharp enough pain for him to feel it. He is lethargic, no energy, no appetite . Today (Tuesday) he continues to have the off and on stomach pain. At times he states the pain moves up to the lower chest area. Visited his dr. Xrays show nothing irregular, strept test came back negative. He woke sveral times last night due to the pain. Dr suggested tums or prevacid. Any thoughts? [/INST] Hi, the pain most probably may be due to intestinal colic In this age round worm infestation is quite common giving rise to pain, malnutrition leading to weakness, lethargy . X-ray will not show anything usually please get a check-up with pediatrician and take treatment. Tb.mebendazole 1 tab 2 times daily for 3 day may be given FPT pain antispasmodics like ecologic may be given, 1/2 tab may be given, HOPE YOUR BOY BECOME WELL SOON. </s>
