I have osteoarthritis by birthright, as everyone else in my family has it as well at relatively early age. In my case, it was kicked off by soft tissue knee injury, then simply the arthris took the oppotunity to take residence.
I went for x-rays, and pronouced to have advanced stage osteoarthritis in both knees. I'm not sure where the early stages went, but I am (was?) a hiker, so I imagine I left them up in the mountains somewhere.
Luckily, either I haven't much pain yet, or am in denial. I do have stiffness, often severe, and use a cane to hobble and take weight off the joints.
After a recent flare up with swelling, the "good" knee went through a period feeling like there were bundles of twigs alonside it rather than tendons, though this feeling slowly faded. The doctor said to ignore the "pains" that weren't even in the knee. So now, while in general much better, there still are these weird mystery pains, well, let's call them annoyances and bothersomes instead, in lower calf, in thigh, etc. Knee itself feels okay.
What causes those strange mystery pains? I assume, with time, these too will pass and I'll resume mere stiffness and hobbling.
Thank you for the great imformation I'm already gleaning from your site!
