Big Toe Joint Pain

The joint of my right big toe started to swell about two months ago.  After about 4 days of swelling, it started to bruise.  All this time it was very painful to walk on, let alone run, so I went cycling.  Turns out that wasn't so good for it either, as it then hurt even without putting weight on it.  After 9 days of swelling, I went to see the doctor, and he predicted gout.  He took an x-ray, which looked normal and did a uric acid test.  The test came back negative, so no gout (thank goodness).  The swelling started to go down after 10 days.  The doctor told me to stay off of it for three weeks, which I did with the exception of walking .5 miles to class and back every day.  I finally went running in the fourth week-just a short, easy 3 mile jog.  I did another hard fast 1.5 mile run a couple days later.  A week after that, the pain came back with much more mild swelling and a slight bruise.  I called the doc, he told me to stay off of it and that's all he could do for me.  I've been off of it for 2.5 weeks, and the pain is not getting any better.  I NEED to be running, and I need the stress relief.  Is there anything I can do to get rid of this pain?  Has anyone experienced this?  I know I need to get another doctor to look at it, but I'm in a small town, and haven't found anybody who really cares at this point, although I do know of a good physical therapist.  Are there any suggestions out there?

Thanks,
