My husband had a farming accident four weeks ago. Two tips and half of one finger were basically crushed in the gears of a mixer. On his right hand, the ring finger has been amputated down to the second knuckle, and the tips of the middle and pinky finger were taken off. He has swelling (a lot) by the end of the day. What is the best way to reduce the swelling? Heat feels good, but I thought it would be better to put ice on it. Thanks for any help.
