I have some cuts that are really red and agitated but they look small and are painless.

Infected cuts usually begin to grow yellow crust or puss secretion like a pimple, in some cases it may begin to turn purple around or even black like a tar. Simple redness and tenderness/itchiness may be due to exposure since it is open and you are more vulnerable to allergies with an open wound. Nevertheless, don't leave even the smallest of wounds without treatment.
