My elbow hurt!!

I got stung by queen bee & this is second time. It must've happened while I was cutting the grass & didn't feel the stung but thought it was just other bug bite which I got some on my body. Horseflies were everywhere yesterday in the backyard. So it start to irritate & swelling ~ I didn't treat it right away because I thought it was bug bite. Now it is wasp stung. It hurt so bad!! I hate it when it happened!!
