The most common cause of groin pain is muscle, tendon or ligament strain. Groin pain may occur immediately after an injury, or pain may come on gradually over a period of weeks or even months. Groin pain may be worsened by continued use of the injured area. Less commonly, a bone injury or fracture, a hernia, or even kidney stones may cause groin pain. Although testicle pain and groin pain are different, a testicle condition can sometimes cause pain that spreads to the groin area. In your case I suggest to visit a doctor for proer examination and treatment. Here doctor may ask you for some test like x ray or scan as per need. I suggest to go ahead for it and later plan treatment as per the diagnosis. If there is a minor to moderate issue at soft tissue level then use of cold pack along with physiotherapy and rest will help to get cure. In case if anything major issue like hernia or ligamental injury etc. As per the diagnosis surgical correction or repair also be needed. And after it again physiotherapy rehabilitation will help you. Here since i have not done physical examination. As per symptoms I have given you some guideline and I am sure it will be helpful if you follow it properly. Take care.
