This pain seems to be from -Varicocele.And as no doctor has done the USG and the color doppler,they might miss this possibility. Surgical Specialist/ or Urosurgeon s- assessment is needed in your case,who is expert to handle a like your son. Treatement- Physical examination from Surgeon with USG of the scrotum and Color doppler scan study of your son s testes and scrotum would lead the exact diagnosis to the Varicocele in your son s case. Corrective Non-Surgical Remedy- Scrotal Support / Tight ugies to support the testes, Cap Vit E-400 mg x 3 mths Tab Zincovit 1 x one a day x 3 mths would recoup his body. Surgical Correction- USG and Color doppler study of the Scrotum to assess the cause and extent of its damage from a Surgeon is to be done before Surgical Correction.
