I had a lamintectomy surgery on l4 and l5 several months ago. I noticed a minor foot drop prior to my surgery, but after surgery my foot drop has gotten worse.. I also developed a severe balancing problem, whereas I can't stand perfectly still for more that a minute. I have no back pain and that it's a blessing, however I have developed these other issues I believe related to the surgery. Is there anyone that had a similar experience? Thank you.
