HI,Dear,Welcome  to HCM.
Based on the facts and data of your query,you Seem to have 2 entities-
simultaneoulsy-
a-Retractile Testes,as the pain vanished in 2 weeks time
 or a Reduced -Torsion testes with -Hydrocele
b-and 
Varicocele which noticed after the hydrocele event.
USG studies would fix the cause of your case.
In my opinion-you seem to have-Hydrocele with Varicocele after Recent Retractile testes event.
Other causes need to be ruled out by 
Second opinion from your doctor which  would help you to plan treats in future.
Hope this would help you to resolve your sever 
anxiety.
Welcome for any further query in this regard
Will appreciate writing your feedback review comments,to help the needy patients like you at HCM.
Good Day!!
