Hi. This can be due to a strained muscle at the point of soreness. Another point to be ruled out - as per the spot of pain you have mentioned::: Torsion of the left testis. There may not be a pain at the scrotum. One can feel only the referred pain. This has to be ruled out as this has a direct bearing on your life. Get a consultation of a Surgeon or a Urologist. Use scrotal support. And most important is to avoid any exercise or activity which caused this pain, till a proper diagnosis has been made.
