I've got a bulging disc in my lower back, and I also have swelling in both of my ankles, legs, and feet. Could those be related? They seemed to start at the same time.
It may be related, but I'd suggest having your physician take a look as a precaution. Swelling in the legs can be a sign of many things, including certain heart conditions, so it's important to take it seriously if it happens more than occasionally. In the meantime, here is a link to good information about degenerative discs and how to handle the pain it may cause. Good luck in your search for answers!
Heck yeah! I've been blessed with degenerative disc disease (thanks Dad) and ultimately spinal stenosis causing bulging discs or "nucleus pulposus". Not only can you get swelling but some pain (phantom or no). I wish you blessings and hope this helped.
I too suffer from this, I strongly suggest seeing a ciropractor
