TL, DR: I have a nopen blister. What to do?
So this happened: I steped on a bee and got stung on the underside of my large toe. During the day after the sting, my foot swelled and formed blisters on the upper side, near the sting. I opened the blisters and applied Octenisept (disinfectant) and Dermatol (poweder of talcum and Bismutum Subgallicum) to dry and protect the wound - this is a treatment I remember from my childhood for wounds like this. Since then I kept the area in the open as far as possible (figuring that it heals faster that way) and apply Dermatol occasionally.
The fluid in the blister was clear, yellowish so I figure lymph fluid. No thick yellow fluid, affected foot isnt warmer than the other one and I'm generally fine. Else I'd have seen a doctor allready.
With googling i found out that Dermatol may not be sold in Germany anymore (since 2003 actually) because there's no proof of any effect.
From looking at this answer, the treatment seems to be "... get the sterile dressing on, then clean and redress (with a light application of an antibacterial cream)".
My problem is with the dressing: Blister-bandaids with a gel inside would seem a good idea, but don't fit the area. A packing of light gauze or something would be doable for now, but I will need to wear shoes or boots soon. Any alternatives?
I assume leaving the foot in the open or at least ouside a shoe is god for the healing process. Is this assumption correct?
