<s>[INST] My two sons age 3 years and 9 years developed red spots on their chest/stomach, on their backs and just starting to go down their legs a few also. The spots have little yellow heads on. They have both had chicken pox and they do look different to the pox because once they have deveoped into the head they leave a tiny little speck spot. Please can you help? [/INST] Thanks for posting you query to Chat Doctor.chicken pox lesion develop in crops multiple vesicle develop same time and are very painful.after 5-7 day heal with crust formation. Second if once person get infected with chicken pox it gives immunity for that infection so second time it does not manifest only the virus remain latent in nerve tissue and some times develop as herpes zoster during adult life. You should contact to pediatrician for taking treatment of this lesion. Hope you would be satisfied with my answer.  Feel free to communicate if any query.regards, Chat Doctor.  </s>
