Hello Dr.Corenman,
I have been having back issues for the past 6 years. It started in the year 2010 and after an MRI it was found that I had an L4-L5, L5-S1 disc bulge/herniation. The symptoms were not being able to sit for long due to burning sensation in the disc area. I also used to get burning sensation in the legs (shin, calf, hamstring, thighs). In march 2015, I injured myself while doing some ball exercises and the disc burst open. The herniation was around 20mm. I had to get operated. I underwent microdiscectomy surgery in the month of May 2015 and have been recovering ever since.
Problem:
I still get burning sensation all over the legs when I sit for long hours. It seems like a cold burning sensation and I feel that the legs have become cold. It starts with the Tibialis Anterior region, then calf and then finally moves to the tip of the thighs. The cold burning improves with rest and I am better the next day. When I start the period of prolonged sitting my legs are not as bad as they are after prolonged sitting.
I underwent an Electromyography(EMG) / Nerve Conduction Test(NCV) test twice after the surgery and it came out to be entirely normal. Post surgery MRIs show no nerve compression. Some of the areas (in the leg) where the burning occurs do not correspond to the L5/S1 nerve dermatome and was told by my doctors that it is not coming from my spine. I also have some scar tissue after the surgery but I don’t think this has anything to do with my burning sensation since the symptoms were present even before the injury.
Any help is appreciated.
EMGs are generally worthless for leg pain without motor weakness as the pain nerves are too small to test.
I assume you do not have arachnoiditis but with that large a disc hernation, that is one possibility if it was overlooked. Do you have bilaterally symmetrically symptoms (equal on each side) or is one side significantly more symptomatic?
Another possibility is peripheral neuropathy. See the section on this website to understand that disorder.
Can I assume that your statement “When I start the period of prolonged sitting my legs are not as bad as they are after prolonged sitting” should be “When I start the period of prolonged standing my legs are not as bad as they are after prolonged sitting”?

Appreciate your help in taking the time to reply to my question.
My symptoms are slightly more on the right leg as compared to the left. But after prolonged sitting both the legs have burning sensation.
I will be getting a skin biopsy test done for small fiber neuropathy just to rule out this condition.
As far as arachnoiditis is concerned, none of my doctors told me I have this condition. I have consulted two neurologists, one in Stanford and the other in Palo Alto Medical Foundation. I can check with them again. I even got an MRI multiple times after the surgery. There was no disc herniation then. The Stanford doctor said that the burning sensation is coming from my spine but the other doctor did not think so.
I am not sure if it is Peripheral Neuropathy as my feet feel okay. There is no numbness or burning sensation in the feet. It is mostly in the shin, calf and thigh region. I also have burning sensation near the disc area when I sit for long. It is worse in the morning.
Can a painful disc cause burning in the legs even though it is not pinching a nerve ?
>>> Can I assume that your statement “When I start the period of prolonged sitting my legs are not as bad as they are after prolonged sitting” should be “When I start the period of prolonged standing my legs are not as bad as they are after prolonged sitting”?
Sort of yes. Prolonged standing is much better (in terms of burning sensation) than prolonged sitting.
What I meant was – at the start of sitting I am okay i.e. burning sensation is less. It gets worse after an hour or so of sitting (without any breaks in between).
Disc disorders that do not cause nerve compression can occasionally cause referral pain into the pelvis and posterior thighs but this pain is specific (called sclerotomal pain). It would start with severe lower back pain and then refer down to the buttocks and legs only then. This sclerotomal pain would not refer down below the knees.
If you do not have arachnoiditis, this could be chronic radiculopathy (see website). You might try epidurals and keep a pain diary to determine if this is chronic radiculopathy (you will have temporary relief for 2-3 hours). The steroid might help to give longer term relief. If you gain no long term relief and your pain is bad enough, you might consider a spinal cord stimulator.

If it is chronic radiculopathy, it must be present all the time, correct ? My condition only gets aggravated with prolonged sitting. Do you think it could be a circulation problem of any kind ?
Mild chronic radiculopathy can occur intermittently but you are correct that significant chronic radic should be present continuously but can change in intensity. Circulatory problems are associated with muscle cramping with activity.
