My 10 month old has developed a red splotchy rash with tiny bumps that look like bug bites. It has come and gone in different places on his body today
Hi... Thank you for consulting in Chat Doctor. It could be any viral erythematous illness. But as you quote them as itchy blisters - the possibilities are Hand Foot Mouth disease/ Chicken pox/ any other trivial viral exanthem. I suggest you use calamine lotion as its giving results along with oral antiallergic like HY Chat Doctor.  Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
