Chronic Health Conditions Discussion and Support

I had an L5/S1 MD about 17 days ago. For the first 2 weeks, I had some atrophy issues, and weak back, but all in all I was much better and my horrid leg pain was gone. All the sudden, on the evening of day 16, I stood up and felt a very very mild version of my former sciatic pain. I panicked and I assumed this mean re herniation. I immediately laid in bed and didnt want to move. I started reading forums, and almost all of them told horror stores of re herniation or problems with scar tissue. I have been careful to do my exercises, so maybe it is some scar tissue that is going to loosen up in time, I don't know.
I was very careful today (day 17) about sitting and how I laid down, and the pain remains very mild. But because of its location and similar feeling to my former sciatica I am still scared. Its good to read here that some people have had similar experiences and that with time, it continued to get better. It could just be part of the recovery process.
I am scheduled for an x-ray in 2 weeks. So I will see how I feel then. Any further advice or insight would be appreciated. I am terrifed to go back to what I had, lying on the floor crying in pain.
