Is this a normal reaction?

Anonymous
When I was play fighting with my younger brother I kicked him in the nuts and I obviously got them really good because he was in a lot of pain...but eventually he had to run off to the toilette to throw up? I was kinda surprised. Is this a normal body reaction to pain in the testicles?

I took my brother to the urologist to have his testciles checked. Besides his testicles having ached and throbbed for about two days, there is no permanent damage. It's all good, I apologized to him, he wasn't mad at me anyway, so everything is fine now. Thanks to everyone who actually gave me useful answers instead of just calling me names and such.
