I did a search on this topic and I got a couple hits but I wanted a few more opinions. I've been trying to go past parallel on my squats and my back has been rounding a little due to flexibility issues. I think this has been causing some tingling in my left leg. I looked online and I'm pretty sure it's sciatica. Have any others experienced this and how big of a deal should I make it? I was planning on lifting anyway, concentrating more on my form, and not going quite as low until I get more flexible. Is this a good plan?
