Hi guys I'm 24. I have been in pain from my left testicle for the past 6 months on and off it's only last month it became constant and I have been in paid eversince. I went to see my gp he felt all round and said it was nothing to worry about and he referred me to a sexual health clinic they took urine and blood sample they also referred me for an ultrasound. It's only recently I noticed a rice sized lump on top of my left testicle should this be something I should worry about. I got some antibiotics from the second doctor. But I'm still in pain I'm waiting on the results.
