Woke up to pee and my entire right side is HUGE! it hurts to put pressure on my right foot , my leg is so swollen it hurts to bend my knee when I walk, and I can't even come close to closing my right hand! This is so WEIRD! glad I have a dr apt. Today. Going to lay down till then so maybe the swelling will go down.
