You would like to know the reason why your testicles hurt you when you vomit and how you can treat it. Vomiting happens when the contents of the stomach are expelled through the mouth as a result of a series of involuntary spasms of the stomach muscles. When vomiting, usually all of the abdominal muscles are in contraction.


In men there is a reflex of the cremaster muscle that lifts the testicles a little upwards if someone touches the inner side of the thigh. In vomiting as the abdominal muscles contract, the cremaster muscle contracts as well. This is sometimes the reason for the pain in the testicles.


According to the data that you described, the pain in your testicles when vomiting doesn’t seem to be any medical condition. However, if you feel constant pain in your testicles not only when vomiting, but in everyday life, especially if you have unprotected intercourse, you may consider seeing a urologist to rule out or to treat infection of the testicles. If the infection is not treated on time, infertility may appear as a complication.


I am not able to give you any further advice online about your medical condition. Please contact your doctor or other qualified healthcare provider such as a urologist for further diagnosis and treatment options.
