I have intense pain in my right foot from my big toe to the bump on the top of the foot please help!?

I have been have intense pain in my right foot since the first or second week of June 2009. The pain is a constant all the time pain and is located from where the bump part of your foot is (near your laces when you have a shoe on) towards the joint where my big toe and bone meet. I'm not sure how I hurt it but I'm a soccer goalkeeper and had a month off and started back playing again the last week of May 2009. I spent the rest of my summer playing soccer 2 nights a week and I wear sandals a lot. The pain has been getting worse and worse so I had an athletic trainer look at it and she noticed swelling and pain and thought it might be a stress fracture (she didn't notice anything with my gait being different or anything like that) so I wore tennis shoes instead of sandals at that point (this was at the beginning of August). I also went to a general practicing at the beginning of September and he didn't run any tests but thought it was my arches falling so I went and bought Orthodox for my shoes and have using those for the past month and no change. On my own with a friend (who's an RN) I did the get my foot wet and leave a print but there's no sign of failing arches as well as I have no pain in my ankles (I read that pain in the ankles is a sign of failing arches). If anyone has any idea as to what it is please help (I don't have very good health insurance so I'm trying to avoid a doctor, also I stay off my feet as much as I can with the exception of what I do for my job).
