I am assuming so, since that is what you indicated. If so, the postiton changes will be important, but I also recommend elevating those ankle areas off the bed surface at all times. You can tuck a pillow or blanket roll under your shins to do this.
Nutrition is very important, esp.
Unless you have dietary restrictions, milk products are a good source of protein. Call your local hospital and ask to see an outpatient dietitian for evaluation. Adding a multivitamin with Vitamin C and Zinc daily is also recommended. Finally, there are many dressings to treat wounds. If you can find a wound care RN at a local hosptial to see to help you make a choice would be good.
