I had a severe L5-S1 herniation back in December 2011 and had a microdiscectomy in February 2012 to repair it. I've been recovering well with just the normal amount of pain and tingling I read about from the nerves healing in just a few areas after the surgery, mainly tingling and pain in my left heel and tightness in my left calf.
However, this past Monday, I was standing and turned and walked and my left leg went numb. It then started tingling. I now have numbness behind my knee, in parts of my hamstring and around my ankle, which are all areas I had numbness before the operation. Up until Monday, I really haven't had any issues with these areas since the surgery. I also seem to have more pain in my hamstring and heel and tingling in my toes on my left foot. The pain isn't as severe as it was before the surgery, but it's definitely more pronounced than it has been the since the surgery.
Is this something I should be concerned about four months post-op? I just started a new job, so I really don't know if I can get the time off to go see my doctor, get sent for an MRI if necessary, and then go back to get the results of the MRI. I'm hoping this is just a bump in the road and nothing serious, but I wanted to get some info from people who've been through this. Thanks!
