Pain in upper right leg

[JRB]

After doing squats again for 2 months now I have noticed a strange pain in my right leg. I may just be sitting down and I will shift my legs and then get this sharp pain in my upper leg. I can squat fine and everything, but when I make certain movements I get this pain to randomly come into my leg. My legs don't feel fatigued or anything, does anyone have any idea of what this is?

Exact location of the pain please.

[JRB]

Front of the leg in the middle area between my knee and my hip.

Try and get an anatomical picture and circling it..that would give the best description
