intense pain in left testicle

i sometimes have intense pain in my left testicle, it feels like someone is pulling on it pretty hard. when i was younger i had an undecended testical (my right one). sometimes my left one tends to pull up to a postition to the top left of my penis, under the skin. what could this be?

Hi there,
Without an evaluation it may be difficult for me to determine the exact cause of your symptoms. Trauma to the testes, testicular torsion, varicocole, epididymitis, torsion of testicular appendage all can lead to pain in testis. Other less common of testicular pain are orchitis,inguinal hernia, kidney stone etc.It may be possible that the cause of your one testis getting pulled up may be related to any of these conditions. A clinical examination is must for correct diagnosis of your condition. See an urologist. Keep me posted.
Best luck and take care!
