I have severe foot pain during/ after running!? HELP!?

From what your telling me it sounds like one of your muscles has a severe tightening at times. Mine does this to and it hurts a lot. There isn't really a name for the disorder but it's a uncontrollable tightening and straining of a muscle. Some people have it in their arms and some even in their jaws imagine that. You should see a doctor however tell him exactly what you told me. There doesn't seem to be spinal damage I've played paintball and I do ride dirt bikes occasionally (Not all doctors are boring some like to be young to believe it or not) as long as your safe about it you should be okay. What I do is before I go to sleep every night I push into the strained area and massage it with pressure, it sounds odd but it honestly does help relax the muscle for the night and all day the next day. It will take a few days to really take affect but it helps a little in the beginning. One story I have though is a lady (a patient of mine name is undisclosed) had the same problem and it actually made her to the unthinkable and cut her muscle apart (she was diagnosed with schizophrenia afterwards) because a "voice" in her head told her to. I feel bad for people like that. I feel good that I get to help them though.
