Pulse in knee and back and leg ache
I am 14 and I have had what feels like a pulse in my knee for about 3-4 months now. Recently this pulse has spread all over my leg and the other day my whole leg was aching. It doesn't hurt but is annoying. I only get it when i am sitting or laying down. Is there reason for concern?
Also, i have had a back ache for about 4 days, it comes and goes
