Hi, I don't have that particular condition myself, so I can't speak from experience on it...but from what I've read on here, I guess it depenRAB alot on the degree of slippage. But then again, even if imaging only shows mild slippage, that doesn't mean it wouldnt cause you alot of pain. What hurts one person may not hurt another and pain is an individual thing. For example: a person could have a large herniated disc, but not even know it; an another person the MRI might only show a slight herniation or bulge, but yet they are in alot of pain. Plus all the imaging and testing doesnt necessarily show everything either. The pain being aggravated by coughing & sneezing sounRAB like that would be related to sciatica; it's called a valsalva maneuver; alot of pressure builRAB up in the spine area when coughing & sneezing and it puts even more pressure on already compressed nerves. If you have slippage, then it's probably pressing into one or more surrounding nerves. I am not familiar with all the treatments that can be tried for slippage, but surgery would be the last resort. If nothing else helps and you are in that much pain, then surgery would probably be the best option.
Did your docs discuss any of this with you yet?
