I hope for you sake that the oil moves and soaks into your bloodstream. I personally do not pin in the quads, I had a bad experience, pinned, oil ran down and collected in my knee depot area, it was one of the most painful experiences I have ever felt, put me out for 2 weeks!! I think yours is either the BA%, if it has EO, there should be no PIP. Also could be that too much is pinned at one time in the same place. You should spread the pinning out in different spots to avoid this. Something that works alot is try heating up your gear a little before pinning, this will make the oil a little smoother going in. Just my 2 cents.
