“Funny story about that actually, so my civilian job, i teach pole fitness to classes of about 14-20 people at once and one day one of my students who worked at a laboratory accidentally brought a radioactive spider to class after they finished working which as i now know is very common. Little bugger bit me and then ran off to who knows where to bite other people.
The initial process wasn’t painful but man growing the extra arms was extremely painful as my body had to grow muscles, veins, bone, the whole she bang multiple times, now though its just slight discomfort, my heart was altered so that it could kind of handle the extra blood flow needed but i still need iron supplements eventually, surprisingly the extra eyes weren’t that bad who would’ve thought. the thorns were a pain in the wallet when i couldn’t control them at first but not much pain physically”
