Hello Dr, Vamika is a preterm 35weeks, mother severe pre Eclampsia, emergency section. she had ARDS surfactant injected and was on ventilator and nasal thongs for 7days. Suddenly, a red 1cm rash appears where we can see skin pores clearly then a water bubble forms then it increase in size may be 1 to 2cms in diameter. It ruptures then heal. this happened 4time. I thought it was due to cockroache bite. is this normal
