Two and a half years ago I had to have Heart Valve replacement surgery. I had been riding a lot in the previous years and believe cycling kept me alive with an undiagnosed heart problem. Anyway after the surgery and my 12 week recovery I went into rehab which consisted of mostly treadmill and stationary bike. I asked the nurse that if I could ride a stationary, if it was okay to get back on the real deal. I was told yes but don't push it. I started riding and experienced discomfort in my left testicle almost immediately. Then over a short period of time the testicle started to get big. It got to the size of a small grapefruit but other than minor discomfort never was very painful. I asked my Cardiologist if any of the Heart Drugs he had me on could cause the swelling and he said possible but not probable. When I had blood one morning I finally broke down and found a urologist. He took one look and said I need to operate! I had developed a Hydrocele in the left testicle. So 9 months after Heart Surgery I had the surgery on my testicle. It was done as out patient but I had to take a couple days off work and wear a tight supporter for weeks after with no riding. Anyway once healed and back on the bike the pain I had leading up to the Hydrocele was gone. I would get it checked out if it stays consistent and does'nt go away.
