I cannot believe this blister is causing more problems than the actual wound.
From what it sounds, you pulled off a scab on the blister and by pulling off the scab (which probably was dead skin mixed with blood), some of the skin tissue came out leaving a crater. The flap is black because it has some dried up blood. I honestly don't think you need to put the flap back on. The blisters/crater will form a new scab and new flap. If anything, I would leave it to air dry (unless you notice that your aunt is scratching it). I would put an antibiotic ointment on it first followed by WBG. If you need to keep it covered, I would put antibiotic ointment first, then WBG, then A&D ointment (but more on the periphery of the blister and then cover it with a gauze. A&D ointment does not allow the gauze to stick to skin so you shouldn't run into problems of having the flap come off.
I hope I understood your question. I am leaving work now and won't be by the computer until later on today. If you want to take a picture and show it to me, I will be happy to look at it.
If the flap is still attached, then don't remove it. I thought that flap came off and you just put back on. Sorry. No, since its still there, just let it be. Not sure if you posted a picture but I didn't get any.
Since the healing was not done, when the top came off it pulled the new tissue that was being made and now there is a crater.
I will wait to see a picture if you can take one.
Good morning Beth,
Yes, I can see it.
Well, as ugly as it looks, it actually is ok looking from a medical perspective. There is no evidence of infection. Black area is all dried up blood. What will happen is the skin will be healing from underneath and replacing the dried up blood.
I would still put a little bit of triple antibiotic on it, followed by WBG and on the periphery, I would put A&D ointment so that gauze doesn't stick to it after being wrapped. Try to keep it open as much as possible, at least when you are around so it can air dry.
Be aware that this will take a while to heal so as long as it is not infected and as long the scab is not being removed, you don't need to worry.
I can see the little flap you were talking about. Keep it attached. The blister itself looks ok but the area around it looks a bit red and dry?? Maybe its just on the photo? Try to use some A&D ointment or Vaseline if that's the case. As the skin heals inside, it will probably push out the dried up blood.
I hope you have a great weekend as well.
