About three week ago, I was at work and started to get strong sudden pain on my left side. It would be severed for a few seconds (teeth clinking) the go away just as fast as it came on. This continue for the night and gradually stopped after a couple of days. It was replaced lower pressure and slight pain in my groin (just above or at my hip). I was unable to get an appointment to my GP so I scheduled an appointment with urologist. He schedule a blood test and ultra sound. I received a call back that I was good on urological level but I should see my GP as I had a fatty liver. Urine test were clean as well.
Fast forward to today, during the afternoon I started having pain in my left testicle. It feels like it is twisted. When I lie on my back or go into the spa the pain dissipates. Pain is not severe probably around a 4 to 5. I have slight lower back pain on both sides as well.
Not sure what if could be and what type of doctor to go see.
