Hello @gravey, and welcome to Connect. Thank you for posting your question about S3 nerve pain in the Chronic Pain group. From my brief research, am I understanding it correctly that S3 nerve pain is related to the sacrum, and in turn could be considered sciatic pain?
If so, I would like to invite some other members who have discussed sciatic pain on Connect previously. I would like to invite @19lin, @gailb, @cheris, @IndianaScott, @reneewise50, and @lowth21, who have all discussed having sciatic pain and ways to deal with it.
@gravey, if your physician thinks it may be an S3 nerve issue, has he or she taken any steps to help with this new diagnosis?

Thank you for replying to my post. I did not respond immediately as I was fortunate to obtain a referral to a top Neurosurgeon who also teaches neurosurgery at university. I was very interested in your response as regards "inflammation of the sacro-iliac joint". I read the results of my pelvis MRI which stated "No accute sacroilitis is demonstrated". I spoke to the neuro surgeon and he has ruled that out at this stage.
My Nurosurgeon has now ordered a new MRI from a new MRI machine which apparently provided a much clearer picture of the nerves. He has ordered:
- MRI - whole spine and GAD
-MRI of the pelvis
-MRN of the sacral neurography PLUS
-Nerve Conduction test of LL inc Perineal
The surgeon mentioned he has been involved in some research of PFCN (involvement of the posterior femoral cutaneous nerve (PFCN), including its perineal and inferior cluneal branches to the symptom of “sitting pain.) which he believes "could" be a cause of my pain possible caused by the epidural durin my prostatecomy some 4 years ago.
I will continue to post here when I get further results.
Thank you so much for your reply to my post

They have ruled out sciatica, as I have never had any radiating pain down my leg, PT is treating me for piriformis muscle, but I have been going a while without much success, so they are starting to consider the S3 nerve, which is one of the nerves that comes out of the sacrum and ties in to the sciatic nerve at some point. I am just interested in if anyone has ever been diagnosed with a S3 nerve issue unrelated to sciatica.
