I had a vasectomy in August and this week noticed a lump in my testicle. Today the lump seems a bit bigger and is a bit painful. Post-vasectomy, I had no issues and no swelling so I assume the lump is not related to the vasectomy. I intent to call my doctor this week, but was curious to find out what symptoms others experienced and if it could be related to the vasectomy. Looking forward to reading responses....thanks.
