TweetI have had this for about 5 years and it now goes all the way down to my foot in the heel to the toes. I have had a couple epidural injections in to the l5, s1 area and they did help. It can be so painful so i know how you feel. somethings that make mine worse when it acts us is, sitting to long, doing a lot of stairs. squats, lunges. They all make it worse and sometimes even bring on the pain. have you had any shots?
