why when u have a bug bite if u itch around it it feels better?

Answer 1

when a bug bites you it injects a bit of its saliva and sometimes poison into your skin which causes itchyness so when you scratch any itch it feels better but try not to, it will keep the wound from healing because itching also means its healing and if you keep any wound open it is vulnerable to bacterias and infection.

Answer 2

You are somewhat calming the nerves that cause the itching. But in the long run it's not good to scratch since you can cause an infection especially with your fingernails that contain copious amounts of bacteria. Try some sort of antihistamine to relive the itchiness if it's bad.
