Ok, so I understand this may sound strange, but humor me please! I had a single level ALIF at the L4L5 on November 24th, so I am about 3.5 weeks post-op. My recovery was going along fairly well, and although I had pain, I felt as though it was more surgical pain and that a lot of my pre-op pains were gone. Last night I was laying in bed on my right size and I sneezed twice. About 10 minutes later I went to roll over and all of the sudden had new pain. I continued rolling onto my left side so I could log roll out of bed and as soon as I stood up I had more new pain. I went to the bathroom and was taking out my contacts and had a twinge of pain that made my knees buckle. The pain is still with me tonight. It feels lower than my fusion point (although I can't really tell exactly) and travels down into my legs. It's not an unbearable pain, but rather an uncomfortable nagging pain. So, I'm feeling a little heartbroken today thinking something is messed up again. Any similar experiences? Any advice?
