Hi, can I answer your health question? Please type your question

Hi there! I’ve gotten big by a bug about 7 hours ago, I never felt the bug bit me, but noticed a bite on my arm so started to itch it, it broke into a rash, then the rash went all red and swollen, it seems to be spreading, as now it’s from my elbow to my shoulder all red, swollen and hard, it also hurts to move ot touch my arm, and I’m not aware of what kind of bug bit me
Thanks, hope you can please help
