Description of intervention(s) / exposure
Interventional group: (RF) group: in which pulsed radiofrequency (PRF) is applied on the genital branch of genito-femoral nerve and ilioinguinal nerve using Neurotherm 2000 RF generator. After sterilization of the inguinoscrotal region, we targeted the genital branch of genito-femoral nerve through holding the spermatic cord between the thumb and other fingers, then, 2 ml of lidocaine 1% is infiltrated in the skin at the neck of the scrotum. a 22-gauge 10 cm radiofrequency needle with 10 mm active tip is introduced towards the center of the spermatic cord and repositioned to obtain scrotal pain at 50 HZ and less than 1 volt sensory stimulation. Pulsed radiofrequency is applied for 10 minutes (5 cycles, 2 min each) and finally 5 ml of lidocaine 1 % and 1 ml of 40 mg methyl prednisolone is injected. For the ilioinguinal nerve , under ultrasonographic guidance the ilioinguinal nerve were identified just medial to anterior superior iliac spine, a 22-gauge 10 cm radiofrequency needle with 10 mm active tip is introduced towards the nerve and localization is further confirmed by producing scrotal pain at 50 HZ and less than 1 volt sensory stimulation. Pulsed radiofrequency is applied for 10 minutes (5 cycles, 2 min each) and finally 5 ml of lidocaine 1 % and 1ml of 40 mg methyl prednisolone is injected. The procedure was done by senior staff pain clinician.

Treatment: Devices
Comparator / control treatment
Control group: (SHAM) group, the same procedure applied for interventional group is done without giving pulsed radiofrequency and instead of 5 ml of lidocaine 1 % and 1 ml of 40 mg methyl prednisolone, we injected 6 ml of normal saline
Control group
Placebo
