Maybe a not so good run

I woke up in a lot of pain this morning.  I think I tweaked/sprained/strained/pulled my hip flexorS.  Yes, flexors.  My right one was bothering me about 6 miles in and then the left was feeling funny by the end of the run.  This morning I could barely get up and putting on pants, forget about it.  I'm sitting at work with a heating pad covering my right hip.  If I could get away with it, I would not be wearing any pants and just have the heating pad directly on my skin.  It is giving it some relief, but I'm going to have to stay off of it and keep stretching.  It sucks getting old.
