My problem is when I walk for 1-2km i feel sensation on both knees. And it seems very hard to walk further. Sometimes my knee bend while walking. Again I sat on floor, it seems very hard to stand and walk. Same thing happens when I climb staircase. I feel very hard and sensation on knees.
I am very nervous my this. Please advise what will i do now?

My age is 35, male.
Sometimes when I straighten my legs, i feel sound on my knees.
