thanks for all the info guys.
It is just above the foot joint.
It was bad already, had it cleaned with antibiotics and desinfection etc. It was swollen...today my last day of antibiotics...
Now the wound is closed with hard blood (whatever that is called). I used to put antibiotic creme and wound creme on it, but this way it kept staying wet...didn't look that would heal.
So since today it is dry...I can wait another week, then I really need to kite daily to get in shape...I have 1 week left then...
I have some bandaid, waterproof, and I am thinking of putting that on, then put bandage on top, then tight it up with tape... I will make a picture

Problem is, I am limited of what I can get here. Antibiotic powder sounds great...would stay dry...
and I have some liquid band aid as well...could even put that on as well...
thx for all the help!
