I am having a rubbery mass between groin and thigh region, feeling to have more liquid in the scrotum but it increases sometimes and decrease (becomes normal) sometimes, another thing i experienced is a bubbling sensation in the scrotum not always but mainly during evening or night it goes away if i walk for sometime do some exercise etc.(undergoing low rbc count and some symptoms of vit b12 deficiency so taking polybion l for it hence there is too much gas in abdomen sometimes) I want to know that it's a varicocele or infection or what else?
