Spides are completely useless. Was bitten by one on the leg while taking a overgrown route during a hike. Didn't know know it then, but just started feeling unwell, weak, and had a huge headache. Still finished the hike. Went home, noticed whole calf is swollen and an obvious swollen spider bite mark on the ankle. Got more dizzy and sleepy. Washed the whole leg in vodka and applied a generous amount of antiseptic cream on the bite. Woke up sweating, cramps all over and shaking. Wife got scared, wanted to call an ambulance. Typical woman, making big deal out of nothing. Just washed it in more vodka and applied more antiseptic. In the morning I was fine, still had fever and cramps through the day, but a lot less severe. Day 3 all good. According to symptoms, it was a false widow spider bite.
