Hi, I m a 17 year old male from India and recently I have been facing this concerning problem. It started today morning when I woke up I noticed my left testicle is larger and stiff compared to my right. It seems that the spermatic cord/ artery on the left is not like my right (which is normal and feels like separate veins). I m experiencing a sagging & dragging feeling on my left testicle and resulting uncomfortableness if I sit for a long period of time, extremely slight pain just as I get up. Apart from that there is no discoloration, no lumps that I can feel, no pain, no problems with urine/erection/ejection, no stomach upsets or nausea . The only thing is the actual left testicle has grown larger overnight by a bit and the area near the spermatic cord is also hard and stiff asif it is one cord instead of threads like on the right. While I know going for a UD is the best medical approach, it also would create a lot of awkwardness as I am a minor. A quick diagnosis to let me know if this is a basic infection or something like pressure I put on the vien would help me decide how soon I should let someone know about this. Thank you.

### output:

HelloThanks for your query, based on the facts that you have posted it appears that you have pain and discomfort in left testicle since recently. This could be due to either 1) Infection of the spermatic cord (Funicullitis) 2) Varicocele 3) Infection of the Epididymis. Ideally one should get it confirmed by doing ultrasound scanning of the scrotum. You need to take broad spectrum antibiotic like Čeferin along with anti-inflammatory Chat Doctor. It should get resolved within a week.
