Hi, I m 50; 5 9 , about 180. I hit my knee on ice while snowboarding about 5 weeks ago. The bruising and pain are gone, but now I have a squishy lump on my knee cap. I don t feel any pain, but I do feel pressure and tightness in the knee. It gets especially tight if I try to do a lunge or a squat. It also feels tight if I do a lot of walking. Will this just go away, or should I see someone?
