I am having pain in my right foot under the second toe at the proximal joint, in the 'ball' of my foot. It is a burning pain and sometimes I can feel a knot under it. Alot of times my toe feels as if it has a cramp in it. Staying off of it helps but I am a nurse and staying off of it is out of the question!!!! What could this be it started about 6 weeks ago when I stepped on a rock and it is not getting any better!!
