Went to see the specialist on Wednesday. Doctor said it's viral infection. This could last for weeks, even months. He prescribed another cream. It's a combination of 2 medicine - Crotamiton and Ge****yein (can't decipher the nurse's writing :-|). Really pity the little boy as it's very itchy. Luckily there's no other discomfort. But he's been a good boy as he stays very still for me to apply the cream all over his body after his bath and he willingly take the oral medicine for itchiness (Antamin).
A few days have passed and new rashes are still appearing. But the rashes around the abdomen area have turned brownish, which is what the doctor expected. I really hope it wouldn't last for months. I really don't know how he got them, the doctor can't give an explanation either.

Hope I didn't spoil anyone's appetite. :p
