I have recently been trying to more frequently stretch and bend in a hot tub and immediately after I get out. Although I arrive home after 9:00 p.m. daily, I am beginning to feel making the effort to get into the hot tub for 30 minutes daily is helping. I have had scar tissue and limited mobility since my TKR, now more than 2 years ago. However, I think there has been some a slight improvement. When I first started doing this, I experienced discomfort in both knees and some burning in the right knee. However, after taking a 500 mg aspirin about once a day and forcing myself to do squats, am starting to feel less tightness and almost no discomfort. Has anyone else tried this?
