HI Traci
A core strengthening program, specific to the region of your lumbar spine in question is/will be key to your success. Internet programs may be helpful for general conditioning, but treating specific segmental joints, it musculature, and key movement patterns are truly the responsible of health care providers. Get some help.
You are not alone, there are many runners with acute, sub acute, and chronic lumbar disc issues training along side you. They are caring for their backs appropriately and able to continue their training. You can too!
Side note: NSAIDS and Narcotic based pain modulators should be minimized, or even better, omitted during aerobic training as they can interfere with performance and general health.
The blister issue sounds friction based. The lube may help. Try to loosen the toe box laces as well.
Have fun out there. Keep us in the loop.
Dr. Greg

Hi Dr. Greg,
From what I remember it was just stretches. They did not recommend any core exercises/therapy/home maintenance care. I believe they did some heat/cold, massage, and no ultrasound. After the MRI came back, I called to make an appointment with the back specialist my regular Doctor recommended but was told based on the MRI I didn't need surgery and care for it would be with my regular Doctor. Most of the time I don't really have an issue with it so therefore hardly bring it up. Sometimes during my cycle or traveling I ask for some pain killers because I struggle during long flights and our my periods. I thinks it's just the inflammation at those times.
I get blisters on both feet. I never struggled with blisters before and I think its my skin getting thinner with age. I'm trying the glide this weekend for my 7 mile run. I'll keep you posted.
Thanks again for your time and advice.
Traci
