testicle cyst or something else?

Hi, I am 45 years old male and from time to time I can feel sharp pain in my groin that spreads to my left testicle. My testicle becomes more sensitive and swollen. I was very scared the first time this has happened, so I went to a doctor and he found out that a cyst had been growing on the in my testicle. A possible explanation was infection, so I got antibiotics. And I got something to reduce swelling. When it began to go down in size, I was relieved of the pain. I think that still there are some traces of the cyst, but I feel much better. I suggest you to have the cyst checked as soon as possible.

MY SON IS DEPLOYING TO IRAQ, HE FOUND A MASS IN HIS TESTICAL ABOUT A YEAR AGO WHILE HE WAS IN TRAINING. HE IS NOW TALKING TO A DR. ABOUT THIS. THE DR. DID AN ULTRASOUND. HIS COMMANDOR NEEDED TO KNOW THE RESULTS A.S.A.P. TO DETERMINE IF HE WAS GOING TO BE DEPLOYED OR NOT. HIS RESULTS WERE, A CYSTS WITH HYDROCELLS. THE DR. TOLD HIM HE WOULD BE FINE FOR DEPLOYMENT AND UPON HIS RETURN THEY WOULD REMOVE IT THEN. NOTE: HE DEPLOYS FOR EIGHT MONTHS. I AM REALLY CONCERNED ABOUT THE WAITING PERIOD. I DONT KNOW IF THIS SHOULD WORRY ME. I DONT WANT TO SAY ANYTHING TO MY SON WHO IS 19 YRS. OLD IF THERE IS NOTHING TO WORRY ABOUT. HE ALREADY HAS ENOUGH WORRIES. I DONT WONT TO MAKE IT WORSE.
