Hello,
Thank you for asking your query at DoctorSpring.
From an Orthopaedic point of view this symptoms does not seem to related to bones / joints or ligaments.
Have you had a Ultrasound examination done for your testes ? What about a urine culture ? Two possibilities I would consider is a chronic pelvic pain syndrome and prostatitis. Have you been under the care of an Urologist ?
You can reply as a followup
Thank you
