Awww Vickie. :( I'm so sorry you had such a painful experience. :( I'm just wondering if that's too much too soon? You are only one month out. Personally, I'd be hysterical if they did that to me back then. I'm thinking perhaps your knee is reacting negatively to all that. Sometimes just gentle stretching at no resistance exercises work better at first, imho. I'm no doctor, that's for sure, but I didn't start getting more aggressive with exercise until month 2 and even then I only felt very sore later on in the day after PT. Elevate and ice that sucker! LOL!
