When I first went to the osteopath for my back i was told I had sciatica from a doctor. Osteopath disagreed and said it was a tight muscle. Then I asked if i should have an MRI due to the fact that back was still painful and was told no wont show up anything on a scan. My GP did actually send me for MRI and it showed up a spine issue bulging disc. The osteopath was wrong to say nothing would show up.
Also I was told not to do my exercise class as too high impac and not to run for a bus etc. My GP said my exercise class is fine and I can do it gently.
I now take anyting the osteopath says with a pinch of salt
