How do you treat cording ( tightness, feels like a cord) under the skin post leg lipo? (photo)

I ended up with skin necrosis post leg lipo of left leg . Had skin graft 8 months ago . I’m dealing with a lot of tightness : cord like feeling under skin around ankles ( both ) and part on side of my legs . Don’t know if it will remain like this . Have compression I still wear that gives me relief ( wear it all day ) ; have been doing lymphatic massage and stretching
