Possible spider bite culture came back g strep fluid drained have low temp antibiotics. 24 hrs later arm red/swollen hot what is meant by g strep?

Serious: It is possible that the spider bite could be secondary infected by group g strep. Also it could be a primary infection. The condition you are describing is most likely cellulitis caused by group g strep. Please, see you doctor as soon as possible so the appropriate treatment can be started.

See a DR: Unless you saw the spider and felt the spider bite you, and unless you brought the spider for identification, assume it is not a spider bite. Spider bites are actually rare, but ignorant people often assume, wrongly, that any incidental sore must be a spider bite. Group g strep can cause infections but are often cultured from normal skin or throat. So you need a diagnosis first before you know wha.
