Went to spinal doc yesterday and he's sending me to vascular surgeon due to swelling in my feet and legs for ultra sound and/or other tests. Had ALIF surgery 12 weeks ago. I have been walking a hour per day and putting feet up 2-3 times per day. I think swelling is due to inflammation from surgery since I still have a little swelling in my back and some pain there as well. Tried stocking again but doesn't seem to help with swelling now. Wondering will swelling go away once back is completely healed? Anybody else have similar problem?
