Sometimes when i walk my right testicle will ache iv'e had 3 negative ultrasounds this only happens sometimes and it only happens walking. am i okay?

Here are some...: At 19, any recurrent testicular pain with a highly variable onset, degree, duration, interval, evolution, resolution, and recurrence should lead a professional mind to consider the odd of experiencing recurrent testicular torsion (twisting). But your physically related only symptoms would urge one to make sure of no musculoskeletal causes. Ultrasound is usually useless if not done at right time.
