Basically, for about 24 - 48 hours, an area of skin (generally from the size of a softball to
basketball) will become extremely tender and sore to the touch
... almost as if it were bruised significantly. It is so tender that clothes brushing against it is painful. The problem is, there is no visual evidence of it. I went to the doctor and felt as though he was insinuating that I was making up the symptoms because he could not see anything. Very, very frustrating.
