Ankle sprain swelling is increased but not much pain after 5 days?

Swelling will increa: -se due to dependency, sitting, as well as a limp does not contract the muscles that are needed to pump the blood & hence the fluid. If you have seen an orthopod and are sure that there is no major damage, use crutches or a cane so you don't limp as much, this and elevate the leg, ankle above the knee & knee above the hip when you can. These will help with the swelling.
