<s>[INST] Hi My son is 4mo. old and we noticed a lump on his penis and it seems that another one is developing next to it. He was circumcised and he seems to be fine (no fever or irritability). and it doesn t bother him when touched and he seems to urinate fine. Can you explain what this white lump could be and if I should take him to the pediatrician sooner than his appt. in three days. Thanks [/INST] Hi, I understand your concern. The lump on your babies penis could be an irritation of local skin (dermatitis). Keep good hygiene locally. Wash with warm water and soap. Apply diaper rash cream locally until you send him to the pediatrician (in three days). If during this time, your baby will get more irritated, or the lump will be painful or any unusual change, should send to pediatrician before your appointment. For the moment, follow the advice given above and wait until your appointment day. Wish fast recovery. </s>
