Hello
In India we treat this type of pressure (
bed sore ) with great care .
First of all take treatment for
diabetes ( if any ) .
Now first of all take precaution in such a way that this wound don't come contact with bed or surface.
I advise my patient to lie down on a tyre ( of car i.e. old tyre ) , put some cotton entrapped in some clothes so that all other side around wound don't hurt . In this way ulcer will not come in contact with any thing and beside it will get air from below .
Wash wound with
hydrogen peroxide three time in day . After this wash it with TERPENTINE OIL .
Now pick up worm which you can see with plucker.
After this again wash with terpentine oil . Now apply
povidone ointment ( very thick layer of ointment ) .
This is local treatment for worms .
Take antibiotics and anti inflammatory drugs from your surgeon.
However , you may not understand few things as mentioned above but I will try to explain in next query.
For urine catheterization is important and plenty of intravenous infusion advised .Good luck.
