Today was one of those drops in the roller coaster ride we're all on. Had a difficult night sleeping. It seems that the little peddling I do drives my knee nuts at night. Every time I pedal for only 5 minutes, I wake up with pain and stiffness the following morning. My PT saw me this morning and my flexibility is still great, I'm still bending at 125/0 even with the stiffness. The surgeon did a lot of work laterally so all that soft tissue needs to heal and that's where a lot of my pain and stiffness is. So, the new plan is to break things up into smaller doses; smaller walks, stretches and smaller amounts of peddling. Then ice the top of the knee and use moist heat under the knee from the thigh to the calf. Do this several times during the day. See if this doesn't help ease things up so that by the time I get to bed, the knee will be ready for a good night's rest. Worth a try.
