i am 27 years old guy,50 KGs,170CM tall.recently i feel a little pain in my balls and it seems like my veins in the left side of my balls are combined in one place. it felt much better when i started drinking lots of water as my doctor suggested me to.however its still feel like its there and whenever i have an orgasem, i shoot sperm more than i ever had then it feels  a little bit pain in my back. does this have to do anything with my sex life?P.S
Good day, and thank you for being with Chat Doctor ! You may have a condition called a varicocele and it's an abnormal dilation of the veins in the testis. It can cause dull pain on the scrotal area, and it can be confirmed by doing a Scrotal ultrasound with Doppler studies. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at
