Hi my right testicle is hard to the touch and hurts a little bit, this has been going on for 3 days please help. ?

Get examined now: The potential causes of orchalgia (testicular pain) are numerous and can be either direct, such as torsion, infection, tumor or trauma; or indirect such as a ureteral stone, lower spine disorder or nerve entrapment. Immediate assessment is imperative especially in the teenage years as certain problems can result in testicular loss if medical intervention is delayed.
