Hello,I have an open laceration on my left hand, opposite of the palm. I am on antibiotics specifically cephalexin, and have bactroban cream. I have it covered with gauze, and an ace bandage and is well covered. Is it safe to use a sauna for 20 minutes, or should I hold off until it has healed up? Also, I did not get stitches because it was too late to do so by the time I got it checked out.
