Just found this board today!
Saw an ortho doc just Tuesday, about MY KNEES! I saw my PCP Friday b/c all I was doing at home wasn't enough to get my twisted-back-in-January knee working right all the time. It's made me reduce my time on the gazelle and cut back on a lot of activities.
So the ortho tells me that I have no cushion on the inside of my knee joints! That space where you have cartilage and the meniscus on that side are completely gone and at about 1/2 what they should be on the other side. He tells me most people find this too excruciating to walk on or even stand on! My options: Surgery to replace both knee joints; Injections - I think they sort of refill that space; Bracing; PT; and pain meds.
For now, I'm going with PT and working on finding the right kind of brace. Also considering temporary use of a walker instead of the 2 canes I've been using.
Before I twisted my knee I only used 1 cane and not all the time either....just on my bad days.
I've used Arnica for pain for years. It must help because I'm not in excruciating pain. It comes as pellets you dissolve under your tongue and as a creme you can apply directly to sore areas.
I also do RICE fairly often as needed for any sore areas.
Looking forward to meeting other over-50s :)
