Dear Dr Coreman
In June 2016 I had a microdiscectomy for a big herniation of the L5 S1 disc that initially caused intermittent leg pain then, after a fall of my bike, weakness in my left calf. I had surgery within 10 days of the onset of weakness.
The surgery was successfully. The leg pain was noticeably reduced and the leg weakness was reducing over time.
I had no back pain before or immediately after the operation.
At six weeks (31/7/16) I was feeling good. I was able to walk for an hour, stand for about 4 hours a day to work at my desk etc. All good.
Then I overdid the exercise, joining my family on a 90 minute hike, mostly uphill. I was still feeling ok so I also rode a bike for 25 minutes. The next day I was hit with really bad leg pain and also new back pain. The leg pain mostly subsided after about 10 days but the back pain did not.
I had another MRI 2 weeks later and this showed no reherniation but there was additional scar tissue. My surgeon said to just keep doing the PT and wait. My family doctor said rest and take more painkillers. I took about 2 weeks in bed then very slowly got moving again. I spent a month on Prendnisone (20mg daily) until mid September. I have been doing PT again for 5 weeks.
The leg pain is mostly gone so long as I don’t stretch the leg much. The back pain is a problem though. I am doing my PT (back and core strength) and the pain is tolerable while I am really careful (1-3 ache with sharp twinges), but I can’t sit for more than 20 minutes, can’t stretch the leg, can’t stand for more than 10 minutes etc. If I do too much I either suffer the same day or the next few days depending on the scale of my error. So I am signed off sick from work etc.
My new doctor (a rehab specialist) has said it is nerve pain due to inflamnation of or damage to the nerve root which sounds right I guess. He said no to steroids either oral or by injection. I asked straight and he said no, I guess because the previous course did not fully fix the issue? He has told me to stick with the PT but I guess that is about supporting the spine rather than healing the nerve right?
I am wondering whether I should really push for the steroid injection as I see you have recommended it to other patients, otherwise what I can do to help with recovery, and last how to judge my prognosis. My current symptoms are really limited my life. I was previously very active and fit.
Many thanks for your help. It is great what you are doing here.
If you have no recurrent herniation based upon MRI (make sure this reading is confirmed by the radiologist) and your pain is mostly lower back pain (not localizing to the side of the previous herniation which means something else), then you are one of the 10% who have developed degenerative disc disease/lower back pain after the disc herniation.
I do think that epidural steroid injections are generally good to treat this disorder along with core strengthening and understanding the biomechanics of this disorder (see https://neckandback.com/treatments/conservative-treatment-mechanical-lower-back-disorders/). These injections may not be helpful but if they are effective, the pain relief will allow you to progress in your conditioning and strengthening.
I like the 20%/week rule to increase activity and prevent flair-ups. I am just writing this section so look for it in the next week or two to understand how to increase activity without aggravation of symptoms.

Many thanks for the very quick response.
Sorry I missed if some key information i think!
Yes the pain is on the side and level of the previous herniation. It is mainly localised about 2cm left of my scar, but it can spread if it gets bad, at the same level.
I had an MRI at 4 weeks when I was going well, then another at 10 weeks at which point the back pain had started. My surgeon said several times that she could see no difference in the disc height or shape between the 2 scans. My new doctor could not see any changes either. The S1 nerve root was looking swollen on both. There is apparently enough space in the foramen for the nerve all the same.
I bought the nerve pain diagnosis as it was consistent with the very fast onset of the pain after my over-exercise day. As part of the diagnosis process the doctor did some stretching/pulling of my leg and caused pain in the leg first, then the back started burning.
On the upside, my leg weakness is still much better than pre-op. I can tip toe for a bit and so on.
I will continue to build up my physio exercises. I am sneaking up by maybe 10-15% each week which I seem to be getting away with.
Local pain that is unilateral on the side of the prior nerve root decompression can be nerve generated and not disc generated pain. I would assume if you “did too much” that you would have pain that extends into the SI joint and buttocks as well as more intense pain at the current location. If so, this is nerve root generated pain.
Continue with your current program as this is the best way to rehabilitate your back. I do think an epidural could be beneficial but is not imperative.

Yes, that matches what is happening. I do get mild aches in the glute and upper back of the thigh. I kinda ignore it most of the time as it is easily tolerable compared to the back pain. I could not say for sure re the SI joint but I have had pain on the bit of the hip/sacrum that protrudes slightly.
So on with the PT. I see the doctor again in 3 weeks. I will see about the injection again. Worst case, my surgeon left this option open when I saw her last 6 weeks ago. She was not keen at the but I got the sense she would not object after another couple of months.
Anyway, thanks so much again. I will do my best to update the thread as things change in case it helps others later.
You probably have residual nerve root inflammation and would benefit from an ESI. Please keep us informed.
