I pulled a muscle in my lower back last week and since then there's been some pain when bending over, but nothing too serious. However, yesterday while I was splitting wood I noticed something strange. The front of my thighs suddenly got a tired/sore feeling, almost as if I had just walked up a ton of stairs. And today they feel sore like I worked out. So I'm thinking this may be a result of my twisted back last week and rather than pulling a muscle I actually herniated a disc. I don't have any pain or numbness or tingling anywhere, just sore and tired thighs (exactly as if I had worked them out the day before). Could this be a slipped disc or is it just a coincidence?
Edit: I don't have this symptom anywhere else on my legs. Just the front and outer sides of my thighs.
