my son has been suffering abdominal pain (whole front area below belly button). two days already. hes been taking enough food though slightly lesser than usual. five days ago he had dark red rashes at the lower leg like some insect bites. I dont know if connected. He has also been having pain on some of his joints (hands and right foot), like arthritis.  he had a cold and some fever last i think before the rashes appeared.
Hi. Thanks for an elucidated history. A combination of the fever and cold indicates viral infection, which might have given a lowered body resistance to cause typhoid like enteritis. The rashes can be due to viral or enteric fever and also for the arthritis like pains. Get consultation with a pediatrician urgently to get a clinical examination and investigations of blood, stool and as ordered. A proper antibiotic and supportive medicines should solve the problem. Remember to complete the course.
