DS had knee surgery two weeks ago. This morning he woke up with a swollen foot and ankle about 1/3 up between his knee and ankle. I had wrapped it in an ace bandage last night to try and stop some swelling but didn't wrap the foot, only from the ankle up. He's in an immobilizer so I was worried about blood clots and called the on call doctor to make sure we didn't need it checked. So when the on call doctor called me back I swear she told me I shouldn't be propping his leg up on pillows at night because that makes it above heart level. She also told me not to prop it up above mid chest when he's sitting because it's above heart level. Did I hear her wrong? I thought you were supposed to prop things up above heart level to reduce swelling. I'm not calling back to ask that, the swelling seems to be going down, but now I'm just confused.
