You should contact the doctor who prescribed you the medication. One way to see if this is a side effect of the medication, is to stop taking it and see if the pain goes away. If it does not than most likely the pain was not related to the Proscar. If the pain goes away, than try taking medication one more time and if the pain returns than you may have a legitimate negative side effect. I have never had a patient with a complaint of testicular pain, but that does not mean that it is not possible.
