Wasn't sure whether to post, given some of the others. The other type of cellulitis hasn't occurred to me but a few people on here have had it and have contributed to other threads I've posted about having it, if you mean the skin infection version.
Can only contribute from having had it but I've had it a few times, worse the first time from a tick bite on my foot which spread, took a few, and stronger, courses of antibiotics to heal it and spend 48 hours trying to keep my leg over my head, took a while but it did heal up.
I also got it following an insect bite on my legs, spread very quickly but responded very well to antibiotics.
These were quite minor episodes though. Hope if you have it you feel better soon.
