It appeared after wearing nylons one night. It appears to look like a white head. To touch it it feels like a bump
with a hard little ball
inside. It doesn't really hurt. I have had it for two days now. It doesn't really look like a blister, more like a pimple. I have noticed one other one before in a different area, it went away after a couple of days. I didn't really pay attention to it, thought it was just a pimple. Any ideas on what this is. Your help is greatly appreciated.
