I just wanted to call attention to some of the best examples I have found of medical authorities talking about the risk of chronic pain caused by vasectomy. We see a lot of examples doctors failing to give adequate warning, so these can be, if not totally satisfactory, at least somewhat refreshing. Hopefully they are the leading edge of a change to a higher level of awareness if this problem and disclosure to patients:
From the European Association of Urology
Post-vasectomy scrotal pain syndrome is a scrotal pain syndrome that follows vasectomy. Post-vasectomy scrotal pain syndrome is often associated with negative cognitive, behavioural, sexual or emotional consequences, as well as with symptoms suggestive of lower urinary tract and sexual dysfunction. Post-vasectomy pain may be as frequent as 1% following vasectomy, possibly more frequent. The mechanisms are poorly understood and for that reason it is considered a special form of scrotal pain syndrome.
From Yale Medicine
Following the procedure, there is a small risk that you’ll have bleeding or infection. Many men also experience minor achiness for a day or two. Although most patients experience no long-term discomfort after vasectomy, about one percent of men encounter post-vasectomy pain syndrome, which means they have an ongoing ache in the scrotal area.

Congestive epididymitis resulting in swelling of the epididymis, which is where sperm is normally stored (1-3%). This almost invariably resolves with anti-inflammatories, ice and rest.
Sperm granuloma is a lump made of leaked sperm that develops at the site where the tube was blocked. Sometimes this can become painful (1-2%). It also almost invariably resolves with anti-inflammatories, ice and rest or may require a local steroid injection.
Chronic post-vasectomy discomfort is a rare complication of pain in the scrotum that can persist for months or years and may interfere with quality of life. Medical or surgical therapy such as vasectomy reversal can be effective, but not always, in improving this pain (1-2%).

Other risks and complications are related specifically to these procedures and, although they are not likely to occur, it is important to know about them. They include a painful inflammation in the testicles known as congestion. This might take a few weeks to appear and is usually temporary. However, in rare cases, the pain may last forever.
