I have had lower back pain issues over the past 40 years. Brought on by heavy lifting @ work or other times and lasting 2 or 3 days, during which Advil eases the symptoms. I also have sciatica symptoms on occasion lasting for the same time and treated the same way. Since the Saturday after Thanksgiving, however, I had lower back pain for about 2 weeks that Advil barely touched but improved slightly each day and have had sciatica pain daily since. The sciatica pain used to go down the back of my right ass cheek and stop behind my right knee, the current pain goes the entire length of my leg leaving my toes with a tingling sensation and the foot slightly weaker than the left.
