you're doing the right things already. Oral meds, keep dry, packed.

Folks, not all "bug bites" are MRSA. There's the normal "Methicillin Sensitive Staph Aureus." MSSA is sensitive to Keflex. MRSA laughs at Keflex. You can try Clindamycin with MRSA, but really, Zyvox is the only good oral med right now for MRSA.

If you redress the wound packing, 4x4s are fine. Unfold them first, and put them into the wound (wet or dry, depending on what you're told). Don't "pack" them in - the wound should have just enough 4x4s to keep the wound open. You don't need to cram 500 4x4s into the hole, when 5 will do. Packing too much actually slows healing.
