There are many patients with prostatitis accompanied by painful swelling in the testicles, perineum or lower abdomen. We all know that these patients tend to have symptoms or worsen them when they are sedentary. Therefore, avoiding sedentary or appropriate activities is a good way for patients to reduce their symptoms. It has been found in a large number of patients that wearing tight pants can also aggravate the above symptoms. And, in clinical work, this situation is still very common. When I encounter this situation, I have to persuade patients to change to loose pants. Many patients do not understand and need to be persuaded repeatedly in several follow-up consultations before they follow my advice. Although not all patients’ symptoms disappeared once they changed their pants. The majority of the patients had a reduction in their symptoms, and some of them actually disappeared. Tight pants aggravate the painful symptoms of prostatitis, probably because tight pants compress the testicles or perineum, causing poor blood flow or directly squeezing the testicles, producing or aggravating the painful symptoms of cramping. Tight-fitting pants include underwear and outer pants. The most typical of the underwear is the pants with elastic bands strangling both groins. These briefs are sexy, but the most direct tightening of the testicles. I generally advise patients to abandon this sexy attire and replace it with loose fitting, fatty underwear. Some patients switch to boxer briefs with legs, and I also advise them to buy two sizes larger. Some patients simply don’t wear underwear, which is fine during treatment, but be careful not to get naked in the summer. The most typical of the outer pants is the beloved denim. The thick, solid fabric, close to the exposed curves of all the sexy masculine charm. But the little brother (especially the two eggs) in the inside is really aggrieved, especially in sitting or squatting when more obvious. Wearing such “armor”, the testicles of patients who work for a long time sitting will naturally be squeezed. Of course, the same problem is also true of the suitably tailored and spiritual pants of today. The solution is to change to pants with a fat crotch, casual pants, sweatpants, once popular boss pants are a good choice.
