Hi haven't used this site in years now as my son is 8 but hoping advice please. My son got first chicken pox spots last Tuesday first couple days not many appeared then Friday and Saturday went mad Sunday even some in mouth went to drs Monday now on antibiotics but today more came out!! Just wondering if anyone else ever had this happen? All sites like nhs say spots appear 3-5 days but its now day 9! Any answers would be appreciated many thanks in advance
