I haven't pinned there before just saw a new spot I wanted to try since my quads are developing, it made it quite noticeable. I use a 1 1/4" and quads are lean, so I didn't think depth had anything to do with it. Thankfully it has subsided tremendously now, but at work last night it progressively got worse to the point I could not bend my leg. I took aspirin and ibuprofen when I got home and iced it when I went to bed. I continuously checked for heat, swelling, and redness all day yesterday. It wasn't even a lump, but i may just avoid that from now on.
