I had mild sciatica 7 weeks ago. No back pain. Had MRI and I have buldging discs. I was doing good and had good physio. Now since 5 days ago my back has started to play up and my sciatica is a bit worse. I do not understand it because the physio was pleased with my progress. I usually wear flat shoes but felt so good with the progress I was making, I wore a pair of slight heels which I have been told are ok to wear. I am wondering if that was the cause. My physio is convinced I can improve further but since my last appointment I have felt worse and my next appointment is in two weeks time and I am wondering if i should bring the appointment forward
