Re: Please help - my husband had knee replacement Hi, My husband had knee replacement on Monday, Aug. 9th. He has had severe pain. We did go to the class before surgery. Everything they told us did not happen. It was a complete waste of time. His pain was unmanageable the day after surgery. They finally put him on dilaudum. Definitely helped. Since coming home he has had a difficult time. Severe shin pain. Even with meds, a level 5. Last two nights he has woken up nauseaus, slight temp and his leg very hot and burning. All in the shin not the knee. Likes his ice machine and the CPM machine. He turned 62 in July and retired immediately. He was a letter carrier and did a lot of walking. He was out on medical leave since January because he could not longer do his job. Luckily he had a lot of sick time saved up from his career in the post office. He needed all of it. We have been told that day 16 is statistically the key to feeling like you can recover.
