I am new so I'll do my best. I have been diagnosed about a year ago with l5 s1 herniation on left side causing only sciatica pain. After a long labor day weekend of kayaking and cookouts (a lot of sitting) I started feeling lower back pain (worse when sitting) all day and night. I'm worried because I've never had back pain and also have my sciatica pain levels at a very manageable level. Am I doomed to now have lower back pain or can this just be a flare up from the increased sitting over the holiday weekend?
