How painful is a wasp sting?

i was in the park with my freind and one stung my freind so i went to avenge him............ also known as charging at the wasps nest lobbing sand every half a millisecond wile smacking them with a 5 foot stick like a chainsaw weilding berserker charging for the person that just killed his family right in front of him

i reget it i was stung in the face and it was like a lit match was rammed in my face

so to treat it put vinegar or an acid on it because a wasp sting is alkalie

but at the end of the day if u dont bother wasps they wond massacre u like Godzilla on a rampage destoring everything he sees
