My son has skin asthma asthma too. We discovered it when he was 6 months. We all the while thought that those red spots (similar to pantal which after 1 day or 2 becomes watery or nagbblister) were insect bites. It appears every time that there's an irregularity sa weather like sobrang cold or hot. Or when he has cough. Or when he ate chocolates or to sweet foods. We borught him sa pedia and good thing, derma naman ang partner ng pedia. They gave us a special soap which costs 500 and good for 2 weeks use but then it takes time before the red spots heal. So we restrict him to eat those bawal foods. Kawawa naman. But then, its really hard not to let him eat chocolates. Then I tried to put terramycin ointment in the spots and the following day, the spots are healed and hindi n ngbblister. The smallest tube costs around P 200 which can be bought sa watsons or mercury. So there but then still need to monitor his food intakes para hindi mrigger yung skin asthma niya.
