I've been away, so missed why your knee is bothering you Sunny, but I am wondering if it is due to arthritis? I suspected I probably had arthritis in my knees & it was confirmed recently by my orthopedic surgeon. Is cortisone helpful? I find going downstairs is much more difficult than going upstairs. One other challenge I've noticed is using public bathrooms - if there isn't a handicapped stall available & I use a regular stall, I have the hardest time getting up, because there isn't anything to hang on to. I hate to pull the TP holders off the walls! Oh yeah - getting down & up from the floor is another new joy:)
Regarding cortisone shots - I've had several in my feet for plantar fasciitis (which FINALLY seems to have gone away after about 5 years!!!!). Each time I got a shot, I had to grit my teeth & try not to cry. I talked my neighbor into going to her doctor & asking for a cortisone shot - I did not tell her it is painful. When I saw her that evening, I asked her if it hurt - she said no - should it have? And her primary gave her the shot, not even a podiatrist. Geesh - was she ever lucky!
