We had given chicken to our son yesterday in afternoon and evening he was having fever @102.00 then we gave him calpol 5 ml his fever came down to 100.3 degree but within 4 hours it rose again to 103.5 so we again gave him calpol but at that time he passed watery stool, again fever came back in 6 hours so we gave calpol for 3rd time, we feel chicken might have caused stomach infection
