My son is 3 yrs. He has lactose intolerance. So we give him nusobee. He has bad digestion. Since birth. Early he never gets fever. 2 times in a year. But always stomach upset problem. Nw from feb he gets fever every month like on 16 feb then 16 march reason was urine infection. Then 16 april after that he gets fever on 4 thjune almost after 1 and half months later. He has cold. He complaints of legs pain in night. For this I started giving him ayurvedic medical after prescription medicine name is pedent for vitamins. Nw he do not say legs are pain. I notice that when ever he has fever there is black pin dot comes in his eye. I did his culture urine test. That was normal. So I want to ask is it common that child get fever in 1 and half months. Or something else.
