I had surgery 8/ 19 / 15. Interlaminar decompression at L4-5, Bilateral hemilaminectomies at L4 - L5., and Bilateral foraminotomies at L4 - L5. Now this week noticed a soft bulge at top of scar. Immediately saw my neurosurgeon on Tuesday, he informed me it was CSF . He wants to watch for a few days. Today at physical therapy they saw it is getting larger and after manipulation of fluid it pooled right back in minutes so then they placed Kinsey tape on it to try and get it to distribute more evenly. I am having late afternoon headaches which go away after laying down for about an hour. Anyone else benefits through this?
