I had a spider bite in 2016 that was bear my right thumb. It turned red and after taking Benedryl all seemed well. I kept circling it to see it spreading outward and kept a wrap on it to hide my “bullseye” markings as it continued to get larger. I showed the school nurse it and it had engulfed half of my palm, including my whole thing, and had a streak going up to my elbow. I ended up going to the doctor that day and they gave me antibiotics for the infection could have turned septic. They gave me ridicule for putting a wrap on it, not allowing it to breathe, but by day one it was red and hurting me. Wearing the wrap helped with the pain. I was yelled at a lot by my parents for making such a big deal out of it, but the school nurse saw the streak up my arm and was contemplating calling 911 or getting me into the doctor that day. I am happy it was spotted and happy I brought it up with my school nurse, for the streak was just going further and further up my arm. I never knew sepsis was a thing until I had that painful spider bite. Thanks for educating others.
