heels and knee pain

So I bought a pair of timberlands today and I was walking around in them and my knees started to hurt pretty bad. Almost like there is this bubble of pain and I need to pop it to get rid of it. I recently (one week ago) dance a bit in heels about 2 1/2" 3 inches long so could it be because of that. When I took the timberlands off it went away in about 15 mins and just now I was dancing and the cramping came back (dancing in heels) so is this a promblem that came out of my recent dancing with heels or is it my body
