COULD THIS BE BONE CANCER?

[JoeClark]

Hello,

For a month now I have had a knee that bends a little more back than the other one
experienced pain in both legs feeling like growing pains but my right knee really hurts as do does the inside of my heel hurt,upper foot which was a bit red and stabbing pain in de knee and ankle and lower leg feeling stiff I am sedentary so I have no injury
my doctor had me take a blood test exept for very low vitamin d(3) nothintg ordinary came out
and I am stopped being taken serious and I don't know what to do anymore
I did gain quite a lot of weight in one month time but that is already been 2 months ago and the pain isn't going away
annoying feeling under and above knee sometimes pain
how afraid should I be for bone cancer I turned 21 today

Please help...

I didn't find the right solution from the Internet.
