Please help me. Extremely painful foot pain. ?

Ok. For the last few weeks I have been visited by and extremely painful sensation on the top of my right foot. The pain is located mostly on top of the foot just behind where the toes begin. I am not exaggerating. The pain starts out as a mildly painful tingle to a very intense "burning" pain. Maybe feels kind of like I am being struck by a bolt of lightening. The pain brings me down, and caused me to have to pull off of the road today!! I do have rheumatoid arthritis and arthritis and degenerative disk disease in my neck. just wondering. Thanks so much for any ideas or if anyone has experienced this. I am a 36/F.
