I am just going to keep my journey so far short because I am sure that many people would understand what the whole journey is like:
Disc herniation in 2015, severe sciatic pain, Chiropractors and Physical therapy didn't help, got epidurals, didn't help. Got L4-L5 discectomy done within 7 months of the injury. But the pain didn't go away. Further MRIs show no more bulge but the surgeon says that the nerve probably got permanent damage and I just have to deal with the pain. I tried epidurals again, didn't help. Got an MRN done, and MRN also shows no damage to the nerve. No one has any clue why my sciatic nerve wont just calm down.
Finally decided to get stem cell injections. The doctor did some fat extraction and injected me with stem cells at around 10 spots. Felt good for about 5 days, but the pain is back again after those 5 days. Doctor has already mentioned that it takes about 2 to 3 months for the stem cells to completely do their thing. It has been 5 weeks so far, but don't see any difference yet. Just wanted to share my experience here. Will update again in a few weeks regarding the progress. If there is anyone in the same boat, please share your experiences as well.
