I am in the middle of undergoing epidural steroid injections for leg pain related to spinal stenosis. Just had injection #2 nine days ago and am noticing a pain pattern similar to after injection #1 2 months ago. That is, significant pain relief in the first week after injection , followed by gradual return of the pain in week 2, but only late in the day. My exercise routine, whether during this recovery or on a normal routine, is to do about 15 minutes of stretching followed by 20-30 minutes on the treadmill first thing in the morning at 3.5 mph. Then I do a 20-30 minute walk with the dog at noon and 5 PM. Typically each day now, I am pain free until late in the afternoon. It's almost as if I have a 'ticking timer' now in my back that says "that's enough for today". If I attend social events in the evening, I'm in trouble if standing (pain level=6). I'm thinking about abandoning the morning treadmill in hopes of lowering my "steps per day" on the theory that maybe I'm overdoing it. If I do all of the above, I would typically clock about 4 miles 10,000 steps in a day on my Fit-bit. I know that walking is supposed to be good exercise, but I'm wondering if I should be limiting myself purely based on the onset of late day pain. When I last had epidurals 3 years ago, I was able to avoid injection #3 based on a successful return to normal after 2.
