Skin abrasion, top of foot 4 weeks ago. healed enough that i can wear socks and sneakers, but my foot is still swollen, not hot or discolored. have been to dr 2x, no infection. how long will this take to heal or what can i do to help?

Lymphatic disruption can take months to go away. especially in areas that are most affected by gravity, like feet and legs. Would wear compression stocking on involved leg, elevate foot whenever possible. A session with a therapist who does lymphedema therapy would also be a very good investment, to teach you whole body techniques to reduce the swelling.Even appropriate breathing techniques help!
