Knee/Calf pain

I am an athlete and I play basketball. I have extreme pain in my knee and calf while running. It also hurts to bend down and then stand back up. I also have discomfort walking up and down stairs, and sometimes walking. I don't know what it is but I would really appreciate some help and answers. Thanks.

it would just be guesswork without a physical exam and maybe some scans or rays---see a doc---ask your pt or coach for recommendation---omhome
