hi, thank you for your query. what you re experiencing is a common injury symptoms due to the sprain of the groin ligaments. In sports, a groin injury is an injury caused by training too heavily,by straigning or rupture of the muscles.The injury is mostly situated near the transition of muscle to tendon or at the connection of tendon and pubic bone . The symptoms in the muscle are often the result of a wrong move while conjunction problems have a more structural cause. I would advise you to- * Cool the injured area by putting ice (a cold-pack) on it for ten to fifteen minutes. You can repeat this treatment once every hour. * Put on a pressure bandage. By external pressure you can prevent part of the internal bleeding. This only works in the muscles antinode. * Stop training, start sparing your muscles. It is quite well possible you will have to look for extra support and use a pair of crutches. if the symptoms persist kindly consult an orthopedician. thank you, wishing you good health
