Has anyone ever dealt with bursitis on one of their knees? Went to the doctor because my knee started to hurt when I went on my knees for push ups and while doing mountain climbers. I was diagnosed to prepatellar bursitis.

It's frustrating because I want to workout but I also know I am supposed to rest my knee. I was told I can workout still but to avoid activities that cause the knee pain/irritation. Would just like it to go away. : )

Any suggestions?????????
