Can someone plesae help me figure out what kind of insect sting i just got? really itchy then bumps then red on pink base but no itch.

Very hard to tell: All insect bites can cause a "local reaction" which includes redness, swelling, warmth and sometimes itch but not pain, at least after the initial bite/sting. Some bugs have a pattern to their bites but identifying the agent of one bite/sting is very difficult if the insect is not seen. Basically, the best advise is to treat is the same way: cleaning, itch control, watch for signs of infection.
