    Hello Dr. Corenman,
    I have written before, but still have an issue and wanted some current advice on a specific question.

    My history is I had a micro-discectomy L4/L5 back in 12/3/2018. There was dural tear that was not discovered until later and developed into a large psuedomengicel, so I had a second surgery 2/7/2019 to repair and suture the dural tear.

    I had an MRI since the 2nd surgery and it showed the psuedomengicel fully enclosed and getting smaller, so it seems the spinal fluid leak is stopped. There is some degenerative disk issues, but not showing a re-herniation. They said they did not see any nerves that seemed to be compressed or entrapped by scar tissue (can you see this well from an MRI?). X-rays showed no spinal alignment issues that would account for this continued pain.

    I never had back pain before the surgery, just sciatica in my leg, but I have had continued back pain and leg/foot numbness since and it has been almost 5 months since the second surgery. The pain is lower back and even into the tailbone. I can’t sit long at all. It is getting some better with time, but the slightest exertion will set me back to more pain.

    I have read many pieces of advice that suggest yoga and/or pilates to help with back pain. However, what seems to set me back the worst is whenever I do any yoga stretches or poses that pull the knee to the chest or stretch the lower back it sets me back a week or more with pain.

    My specific question is, do you think this stretch hurts because I am too tight and I need to push through the pain and just continue doing it? Or, am I best off not doing anything like this that I know makes it worse and just give it more time? If this is caused by some sort of nerve adhesions and it is just going to continue unless I can break them free then maybe I need to push through the pain. But, if it is caused by nerves still healing and needing to not be irritated further until they heal then I don’t want to do anything that further irritates. Just not sure what option I should take here. Thanks for your advice.

    MRIs are generally accurate for nerve compression and scaring but since the MRI can resolve down to about 2mm, there are some things that can be missed. “They said they did not see any nerves that seemed to be compressed or entrapped by scar tissue (can you see this well from an MRI?)”.

    Back pain after a microdiscectomy can be generated by a degenerative disc as the disc can be incompetent (by definition or you wouldn’t have had the HNP in the first place). If the back pain is only on one side (the side of the herniation) and always accompanies the buttock/leg pain, this pain can be nerve root related. However if the pain is central and can come on independent of the buttock/leg pain, it probably is discogenic in origin.

    If stretching the hamstring triggers the pain, this is the same maneuver as stretching the sciatic nerve. This can cause immediate pain or delayed onset pain (6-12 hours later) and is an indication of either a continued fragment compressing the root, adhesions or chronic radiculopathy (see https://neckandback.com/conditions/chronic-radiculopathy/). Maybe consider a selective nerve root block to calm down the nerve (https://neckandback.com/treatments/epidural-injections-and-selective-nerve-root-blocks-diagnostic-and-therapeutic/).

    Thanks for your reply. Would it be an acceptable strategy to just try to not do anything that I know aggravates the nerve for awhile and see if it will calm down on its own? I assume the only reason to continue doing the hamstring stretch would be if this chronic radiculopathy is caused by adhesions then it may help to break those up, otherwise it would be best to just not do it since it causes the nerve to be more irritated right?

    If the nerve root block is very advantageous for healing and actually contributes to the healing then I would consider it, but if it is just to relieve the immediate pain while the natural healing takes place then I can deal with the pain. Is that the case or would the nerve root block aid in the healing? Thanks.

    This is the art of medicine as there is no absolute rule to follow when stretching the root. Too much and you will “pay for it later”. Too little and the scar can contract, shortening the root even more. There is no penalty for waiting. Time is on your side. The nerve block can accelerate healing and break the pain cycle but there is no guarantee.
