I have athletes foot on one toe, and when a blister-like bump is about to pop up, that spot tingles. is that normal?

Wrong diagnosis: "Athlete foot" generally refers to fungus infection. It is very unlikely to involve just 1 toe. You will best resolve this by exam at a dermatologist. You need a precise diagnosis so you will know what to expect and how to proceed.

Sounds abnormal.: Herpetic whitlow comes to mind, but you need to see your doctor for diagnosis and treatment (of both conditions).
