3 weeks ago the (side and up) of the left arch had a burning sensation. Today it is severe.(Burning sensation and pain). The area also appears swollen. It is getting very difficult to walk on it. Any ideas ?

If it continues you should go to the doctor. I knew someone who walked around on a broken foot for days, not knowing it was broken and ended up having to get surgery.
