I have similar issues, there are nerves that go from lower pback into scrotum, I rarely have back pain without testicular pain. I also have epdiditymitis which does not help. Just a thought if the other possible causes do not pan out. I was clear for all the other causes.
I looked up the symptoms for kidney stones and I'm thinking that might be what it is. I won't be able to see a doctor until this weekend though (3 more days). That should be soon enough right? The pain has died down a little but it's still there.
Welcome to the MedHelp forum!
The pain in testicle and lower back or abdomen can be either due to stones in the urinary system or due to inguinal hernia. Other causes too should be looked into if these two causes are not found to be causing the pain. It could be due to varicocele or spermatocele or cancer. An ultrasound of the testicles will diagnose cancer, varicocele and spermatocele. An excruciating pain is often due to testicular torsion and needs surgical intervention ASAP to save the testis. Aside from orchitis and torsion, this can also be due to problems with the protective structures mentioned, testicular dislocation, epididymitis and even hematoma or bleeding. Please consult an urologist or your PCP ASAP.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
