Hi there ~
I understand your concerns. I believe that you have pain in your testicular region as well as headaches
along with the hernia
that is healing after you had it treated surgically laparoscopically. I also believe that you will do well with consulting a qualified doctor to get to know what you can do for your back issues especially since you have had a history of problems with your lumbar discs. It will help to consult a doctor for this as well as probably an infection in your genitalia or the urinary tract
for which you need treatment. I hope this helps.
Take care and have a lovely day!
