My physical therapist saw my MRI and said “WOW! You sure have a long tail! Does it hurt to sit? It should.”
With no other frame of reference what do you say to that?
Oh, and as for diagnostics ever being “way off”… don’t hold your breath. So much comes back normal (as read by1 person) its not even funny. That’s why so much credence is give to symptoms for us. Imaging and tests are often out of proportion to the trouble being caused.
Do you have a lumbar and sacral image you could share? You have me curious now. If you show me yours I’ll show you mine. 🙂
