Need help docs! my 3 most left toes on my left foot are red swollen and itchy. why?

See a foot doc: You could have an infection which developed from athletes foot. There are other possibilities as well which is why an exam is prudent, .

Red and swollen: As said - could be a secondary bacterial infection as well as other possibilities. See your podiatrist asap

Not normal: sounds as if you could have a fungal infection. see general PCP or podiatrist.
