Discomfort experienced in a testicle can arise from various sources, such as minor trauma, a rupture in the testicular wall resulting from a direct impact, orchitis (inflammation of the testicle), epididymo-orchitis (inflammation of both the testicle and the epididymis), and testicular torsion.
Occasionally, the source of the discomfort remains elusive, and the pain subsides on its own without the need for treatment. In cases where there is a tear in the testicular wall, surgical intervention might be necessary to mend it.
