I ruptured a lower back disk (I want to say L4/5) maybe 10 years ago. Had excruciating pain on and off, and have had 2 MRIs maybe 3-4 years apart afterward. Bulge is seen to have shown to have shrunk quite a bit between those MRIs and more or less, I am pretty normal. I play raqcuetball twice a week, can walk/hike for hours on end. Only thing I can't do is stand around (the "museum" walk) and lie on my stomach for more than 5-10 mins. In the recent 3-4 years or so I have been having a different issue that I am pretty sure is related. The front half of both my feet go numb when I sleep, feels like they are freezing cold (I used to get up and run hot water on them until I finally felt them and realized that they weren't cold at all!!). Up until the last few months, I could just lay in the fetal position, or ball up face down for 5-10 mins and it would go away (all makes sense when you understand the bulge, spine/nerve geometry....I'm an engineer). But lately it has gotten worse, my toes ache most nights and it is very hard to get them to stop. Curling up sometimes works, but often not. Most of the time during the day they are fine, maybe slightly numb, but doesn't bother me. I have no movement strength issues in my feet when this happens. So my question is, am I right to assume that this is still an issue related to the disc injury? I have other (mental) issues that keep me from sleeping sometimes, and I know that this aggravation might just be the thing that I focus on. But wondering what else I can do, stretches, positions, etc. I am looking to try an inversion table. Any thought suggestions appreciated. I am 54 years old BTW.
