leg pain after chest day?

[jmancini4588]

Well yesterday I did chest on one of my sets of weighted dips ,I felt my legs get very tight, but nothing after that. Then this morning I wake up to an incredible burning pain in my inner thigh. It's right above the knee cap on the inside of my left leg. After doing a quick lookup I found that this appears to be the muscle in question http://www.exrx.net/Muscles/Gracilis.html . The thing about it is that I would never notice it unless I touch it. I can walk, extend my leg, etc. As soon as I touch it though it feels incredibly painful like a shard burning pain. Anyone have an idea as to what this is.
