How did my botox stop working after popping what I thought was a pimple? All the muscles that didn't work now do. (photo)

This is going to sound crazy. I got botox yesterday morning. None of the injections hurt except one by my temple. Later I developed a pimple there. today I squeezed it very gently and a lot of clear liquid came out. Immediately after, my forehead started tingling and I could feel all the muscles that I wasn't able to move moving just fine. I looked in the mirror and everything was back to before botox. I was showing everyone my inability to frown or wrinkle my forehead. Now it's gone. HOW?
