Lynker, I had sciatica for quite a long time, I tried all the exercises recommended and physio, apparently this cures it in the majority of cases. I did have a problem with my disc's and even had injections directly into my spine to no avail. Surgery was my only option when eventually I could barely stand. I was unfortunate and had to have 3 surgeries the final one 9 years ago when they fitted rods and screws. I've been as fit as a flea since. Go to your Dr and get early diagnosis, you may just have a trapped nerve, that exercises may help but worth knowing sooner rather than later
