Hi on the 18 August 2018 I had alif surgery, the first 3 weeks was heaven I had no back pain just a sore tummy in wound area and felt like I d done a 1000 sit ups. After 3 weeks my left bottom cheek start to ache then spreading across my lower back and struggled to lift my left leg as it hurt so much. I saw my specialist 6 weeks post op and he said my sacroiliac joints had become inflamed. He said he would normally see me in 6 months but said he wanted to see me in 6 weeks which is on the 20th Nov. I have pain in coccyx area and when I do pelvic movements it hurts. My psyhio said it was my piriformis that s playing up and I need to do stretching to release them. If this is the case and I do the stretches why doesnt it release off? I can be ok for a short while and then it starts in my bum again. Today has been an awful day, I changed a light bulb and with my arms up my higher back felt like I d been stabbed where my bra sits and I couldn t get my breathe for quite a while. Please can you tell me what s happening! I stand to lose my business and everything if I can t get back to work soon, I m a self employed painter/decorator. I m 11 weeks post op and just don t feel stronger enough to go back to work or confident enough with this awful ache and pain. I worked for 5 years with a bulging disc and looked for answers every day about my back, after going private and having a alif the last thing i thought would be me looking for answers again. Please help King regards Eleanor collins

Hello, Hypertensive & obese patients may experience complications post AIF surgery. The complications cause instability of the lumbar spine & chronic diffuse, dull, lower back pain.  You are suggested to visit your surgeon to get a follow-up treatment done. You need to get physically examined to detect any infection, bleeding, anesthetic complications, nerve damage, adjacent segment disease, non-union, degenerative disc disease r Islamic spondylolisthesis. It may take 3 - 12 months to get solid fusion. Your surgeon will decide whether you should wait for the symptoms to reduce or you need another spine surgery if the healing time is taking too long or if the discomfort to too much to bear. Hope I have answered your query. Let me know if I can assist you further.
