Soreness Shift (Quads)

I had my third pin on tuesday (it is now thursday night) and the soreness shifted last night from upper quad to having some tenderness a little bit above my knee. Soreness at the injection site feels okay just a little bit tight. Do i have anything to worry about?

It was post cardio on the bike (30 mins on high resistance) after a little bit of flexing/posing practice.
