Question
I have had a corn (keratosis) debrided (podiatrist), excised (podiatrist), and then when it came back again, debrided (dermatologist) located under the third metatarsal.  The podiatrist said it was from a blocked eccrine duct, while my dermatologist said it was just a corn from pressure.  It came back within days the first and second time.  I waited for the dermatology appointment about a month, so it was quite painful by the time I got there.  One Tuesday, he removed it, it felt better (though not painless).  On Wednesday AM, the sole of the foot was swollen.  It does not look red or infected, just fluid filled and I bet this was happening in a milder form before the last removal because it hurt upon wakening the most. I have spasm like pains in the first metatarsal like an involuntary sqeezing while resting. The big toes burns and itches a little.

Should I call the dermatologist?  Wait to see how much it goes down (as I type I noticed a little reduction)?  Go to my primary? Is this common?

Answer
It is not common.  You should call whoever treated it last (your dermatologist if I followed correctly) to make sure it is not infected.

All the best,
