Its almost a year and a half since I started experiencing severe, but infrequent lower abdominal pain. The pain would last for  2 - 5 mins and would go away. It would then comeback after days, weeks or months. Possibility of inguinal hernia, kidney stones or any major development was ruled out after tests and scans(MRI and ultra sound) . My doctor gave me medicines for urinary infection. But the pain still comes and goes. It is mostly very sharp around the lower abdomen and would increase when I stretch (as in a yoga posture, standing with hands up, bending to the back). I am not able to say if its those testicles causing pain. The pain is usually sharp, around lower abdomen and rarely dull pain around scrotum. Any help is appreciated. Thank you.
HI. Read the history carefully. It says the pain is sharp- 2-5 minutes-increases on stretching-dull pain around scrotum and so on.... As your investigations are negative I would think of a muscular cause and may be an entrapped nerve causing the sharp pain and referred to the scrotum. I would advise undergoing the high resolution ultrasonography of the abdominal wall; mark down the site of pain when you get an attack. This will help for a pointed investigation.
