Thank you for asking your query at DoctorSpring.
You should leave the blister alone. The blister is a newly formed one and so it is rather full. The blister will provide a healthy environment to heal and new skin formation. Being on the joint there might be slight discomfort. You can just have cotton wrapping over it. (Not very important).
I assume you do not have pain or any other symptoms.
The blister may rupture by its own in 2-5 days. If that happens, just wash it using clean water. The skin will peel off after some days.
Unless there is severe pain or discharge no further treatment is required.
Hope this helps
Please feel free to ask followup question.
Patient replied :
We have kept it covered. About a day later the blister broke. For two days now we have kept it covered and changed baqndages daily or twice a day. It has been wetting the gauze a little bit. The skin sometimes appears to fill with fluid as if the leak hole repaired. We marked tiny ink marks around the red zone to see if the red spread such as in an infrection. It has not spread. It does not smell. At what point would we remove the dead covering skin or wash or treat the area in any way? What should we do next? What should we watch for that might let us know if we need to actually go to a doctor? I have attached two more pictures.
From the appearance the burned skin surface is yet to heal. but there are no signs of infection. You can expect noticeable improvement in less than a week. The dead covering can be removed if you have sterile cutting scissors. Since it is unlikely you can leave it alone so that it will peel of by itsown. Bandages are needed only if you exposed to dirt / soil etc. Even if you are applying a bandage apply a light bandage withour much pressure.
Watch for pain, increasing redness,increasing swelling in and around the burn area & continuous discharge - if any of these are there you might want to visit your Doctor. Even after a week if the blister stays so without any improvement you can get in tocuh with a Nurse to remove or break the blister.
Hope this helps
