Hello Doc, I am 42 years, my problem is L5-S1 bulged disc, this was found when I went for a MRI in March 2011, I have been having this back pain almost 24 hours a day and get this tingleness in my left foot on and off. The main problem is I can't sit for more than 20 mintues on my office chair. I can walk and drive my car without any problem. I am considering to go for percutaneous disc decompression procedure, please advise.
