Hi, thanks for writing to HCM.
Basically Lumbar plexus block is indicated for Hip surgery
, Anterior thigh & knee surgeries. I just don't understand the rationale and logic of lumbar plexus block in back pain
Anyway,an MRI scan of Lumbar spine
is needed to know the exact cause of back pain.
The possible complications after a lumbar plexus include - Infection, Hematoma formation, toxicity of the local anesthetic
drug, risk of nerve injury
I personally feel that the cause for increased pain after the procedure could be due to either infection or due to formation of a hematoma.
A thorough evaluation is needed to diagnose the exact problem.
Hope this information is helpful. Good day
