Thanks for the query.
It is indeed unusual to experience any hardness in the testicle. It could be indicative of an inflammation, long standing infection or even a benign or malignant tumor in the testis. This definitely documents a visit to a general surgeon for an examination and further investigations like blood, urine, and biopsy tests if required. In case of an infection or inflammation, antibiotics would help. A tumor might need a surgical excision.
Hope this helped.
