@Raffs my PT said that when the knee is worked hard you can expect to feel the ramifications anywhere from 24 - 48 hours later. That's probably what happened to you. Every time we work that knee we're breaking down scar tissue, and when we stop we create more. Seems crazy, but I guess that's how it works. Yesterday, we tried something a little different to try and get me a better night's sleep. Work out several times during the day in small doses. Ice the top of the knee, moist heat behind the knee. I did that at least 4 times yesterday. To my surprise I only had one instance of pain last night. Quite a difference from the 3-4. I don't have too many issues during the day, it's night. So, we'll try it again today and see what happens.
I need to try this tonight. Thanks for posting.

. I've just had my first trip to Aldi, boy do l know how to live it up!!! I'm now reclining on the sofa with my cryocuff wrapped round my knee. My knee was quite stiff walking around.
