Itchy Toe Blister

For 2 years the toe next smallest toe have been itchy. I applied the normal athletic's foot sab. All the over counter medication does not help. The itch will stay for about 2 to 3 weeks then go away. Now, the itch is accompany with a throbbing pain and blister (white about the size of a pea). I consult my doctor. She only gave me more expensive sab that does not reduce the pain or make the blister go away. The only way I can releive the pain is to soak my foot into ice water.

I only wear sandles. I only wear socks during the winter. The itch still comes back every other month.

Any suggestions?

I have read a couple of systems from this sight. There are a couple that are very close to the same systems that I am experience. I did not see any answers the the blogs. The closets blog is one from diane9 on Jun 27, 2002. I would love to know if Dr. Alan Rockoff, M.D. was on the right track. I don't want to go to 14 doctors like diana9 did.
Any news...?
