Health advice asap

About 3 days ago my leg just randomly starter Itching I was busy in the kitchen so I didn't  get a chance to look down at it. Then when I finally sat down I noticed a huge "mosquito bite" well that's what it looked like. Red, puffed up, and really itchy. I didn't may any attention to it. The next day I spent the whole day in pants and didn't look at until
I was getting ready for bed and that's when I got a little worried. In the same place where i got my "mosquito bit" a whitehead pimple appeared . The skin around it was a little red and it was still itchy. I put a bandaid on it and continued my day. The next day (that's today) my husband told me I should pop it and disinfect it. So I gave him the honors. He cleaned it and lanced it. Put a cotton ball on it with some surgical tape. Anyway I went online and read some "crazy"
Stuff about staph. So now I'm
Kinda nervous. Should I be ? Thanks for any advice in advance ☺️
