@arffaderm: #dermatologist tries #bugbite suction tool. #bugbitething While it would be cool if suction tools actually worked unfortunately biologically it doesn’t make sense. There are also no clinical trials suggesting it works. First off, the only studies we seem to have about “sucking out venom” comes from snake bites and those studies show no benefit. Medical professionals actively recommend against sucking out venom as it likely will cause more damage (like injury to the skin and an embarrassing mental image of you try sucking it out with your mouth) than benefit. The same likely applies for bug bites. . The biology behind why this wouldn’t help also supports this. The rash and symptoms you get from bug bites are caused by a tiny amount of saliva causing a large inflammatory reaction (mainly histamine induced). Once the saliva causes the reaction you cannot reverse it by removing the saliva (it’s like trying to remove a domino that has already fallen thinking it would help more dominoes from falling - that ship - er domino - has sailed) the histamine has been released and the immune response is underway - the swelling and itching is your body getting mad about something that already happened. . Treatment then should focus on stopping the histamine induced inflammation - icing can slow inflammation, topical steroids stop inflammation, and antihistamines block histamine - the main stimulation for the inflammation. . The only two scenarios where I could see why people love this device are 1) the placebo effect - you believe it therefore your mind makes it seem like it’s working. 2) counter stimulation - like when you have a headache and your sibling stepped on your foot the pain or sensation from the other stimulus temporary blocks you from perceiving the itching stimulus. Once the counter stimulus goes away, the itch returns . Come at me in the comments. Did I just help you save $10 or did I waste your time?
