I'm experiencing some discomfort after masturbating. It's like a tingling sensation starting from my left testicle, moving down to my left thigh and foot. Plus, whenever it's hot, I feel some discomfort and inflammation in the veins on the left side, and honestly, it seems a bit more swollen than the right one. There's also this mild back pain that I notice, but it usually gets better if I rest properly or use an ice pack. I was treated for epididymitis on my left side around two years ago, and at the time, ultrasound results came back normal even though the discomfort lingered. This issue shows up randomly, and I'm getting a bit worried. Do you have any advice or thoughts on what might be going on?

During this act, due to excessive force there might be injury to the genitals which may be the reason for your symptoms...urinary tract infection may be the cause... There are evidences which suggest that excessive masturbation might aggravate hair loss and it might cause premature ejaculation which will cause difficulties in concieving in the future. So I suggest you to do yoga and mainly meditation to have some willpower to control your habit.
