I have some pain in my legs, feet, and some light redness with swelling after 9 weeks post-op ALIF. I wonder what causes the swelling? Is it the inflammation from the nerves trying to heal and my body accepting the fusion? No one has explained this to me. However they did tell me NOT to take any anti-inflammatory meds. I have had my first herniated disc for almost 8 years and the second one was noted on the MRI early this year. I guess this healing process will take a long time for me. Please discuss your thoughts on the cause(s) of the leg and foot swelling.
