 [ Symptoms ] i am currently 64 do i have to sign up for obamacare [ Disease ] sorry you are experiencing this do you know what is causing the swelling for instance did you injure your knee in some way or did it suddenly just balloon up do you have a prosthetic knee knee replacement the reason i ask is because any of those things could cause swelling and the treatment might be different for each cause you are doing the right thing by elevating your knee the ice is probably ok if you think the swelling is due to an injury otherwise the ice is probably useless and at that ice generally is only indicated for a few days post injury if this is a chronic problem you have had it happen before or if it does not clear up within a few days or if the swelling is accompanied by redness and heat in the joint plus a fever then i would suggest you seek medical attention hope this helps and you feel better soon
