An update..
My MRI is now a CT scan, will be the first week in September. My wife received a lovely phone call from the urology specialist surgeon who we saw a few weeks ago.
I found out my wife secretly emailed him with concerns to the amount of pain that I have been in recently, struggling to walk etc. He was replying to her email with a personal phone call, how amazing was that. Not only I have to thank my super incredible amazing wife for thinking of me, also the top urology specialist for taking time out of his day to personally speak to my wife, how caring is that...
Reading between the lines, there may be cause to believe the pain I feel down my legs into my feet could may well be the sciatic nerve. The trigger point for the pain seems to be originating from the testes, so what ever is going on, I just hope it shows up on the CT scan.
