sorry you're 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're 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've had it happen before) or if it doesn't clear up within a few days or if the swelling is accompanied by redness and heat in the joint plus a fever then i'd suggest you seek medical attention. hope this helps and you feel better soon!
