What could be the reason for the pain in my right big toe?

Hi doctor,

I have pain in my right foot in my big toe, the inner side of the top of my foot, and the outer side of my ankle, just below the knob of ankle. It comes and goes and is sometimes fine, but when it is there, it is pretty bad, burning, and very intense, and I sometimes get pins and needles. It is usually worse when sitting down, but sometimes I cannot put any weight on my big toe without a bit of pain. It has been going on for about a month, but it was not that bad. First, it was just on the top of my foot, but the pain has spread this week and has gotten a lot worse. I thought I would be sick earlier; it was so painful and hard to concentrate on my job. I cannot think what has caused it, I have tried Tablet Paracetamol, Ibuprofen and Aspirin, and the Deep Heat cream, but none of them have helped.
