Weird lump on side of my left leg?

I've had a lump on the side of my left leg for awhile and i went to the doctors about it and I've been having ultrasounds and x-Ray's, and I have to wait another few days for my appointment with the doctor about what's wrong and it is stressing me out a lot around test time and all that and I was wondering if someone could give me an idea of what might be wrong It's a painless lump by my knee unless I do a lot of exercise, then I get pains On the x-Ray it looks like a bit of bone is growing out from my Distal Femur Any ideas?
