Hard to believe it's been over 4 years since being struck with a herniated disc. As known to most, herniated discs don't heal, but with some luck they shrink and take pressure off the spinal cord. For me, there are the occasional flare ups and annoying tingling down the left leg, but other than those, life has been pretty normal.
I avoid lifting heavy objects, do conditioning exercises every morning, and walk daily. There's plenty of running too every other day, like 12 hilly miles this past weekend. I ran a marathon last year in Hartford, CT with no ill effects on my back and this year I'll be running the New York City marathon.
I guess the point is that a herniated disc doesn't necessarily mean having a disability, at least based on my 4-year track record so far. If you have it, be patient, treat it with care, and with some luck it'll just be an occasional minor inconvenience.
