Q: 

What must be done if an ulcer occurs from pressure or friction  
from the prosthesis?

               A:

 1.  Stop using the prosthesis temporarily. 
 2. Clean the ulcer and apply an antiseptic such as betadine.
 3. When the ulcer is healed, try using the prosthesis again. If the ulcer recurs, 
     go to see the  doctor or prosthetist.
