Apparently yyour knee is slightly swollen. Since you feel unstable the reason might be a meniscus damage. This can develop by trauma (falling and distorting the knee) but also without any movement at all. Depending on your age and the strain your knee had to bear dring the last 20 years (accidents, sports...) it can just degenerate. Little fissures and bigger damages can develop. Acute traumatic meniscus damages tend to hurt, chronic ones quite often don't.
So please see your doctor or go to E.R. to have checked if there is water in your knee and if the meniscus signs are positive. These are certain painful movements.
Depending on the outcome maybe an operation will be necessary.
Inflammatory (rheumatic) diseases can also cause such a swelling, but are painful, especially during nights.
If there is any question open feel free to ask!
Thank you, ***** ***** is obvious. Do you ski or ever fell down heavily?
No, I don't, because clotting causes edema in the whole calf and pain.
This swelling seems related to the joint.
This is rigfht. Clotting affects the veins, by the way, and has nothing to do with the arteries that bring the blood into your toe.
You arer right. The doctor has to examine the knee and see if some cooling and rest might be helpful enough.
