<s>[INST] my grandson was determined to be a carrier of strep. second week of dec he had tonsils and adnoids out. can he still be a carrier? i get erythma nodosum and it was going away until i spent time with him, now i got ten times more lumps than i had, and i wondered if being exposed could have made it get worse. [/INST] HI, thanks for using Chat Doctor It is possible that he is still a carrier. His doctor would be able to determine this by performing various swabs and other tests. Erythema nodosum is an inflammatory condition that is characterized by inflammation of the fat cells under the skin.  Though the cause is not found in the majority of persons, strep infection is one of the possible known causes. I hope this helps </s>
