[Headache and low back pain after epidural anesthesia].

Headache and low back pain are common minor complications after epidural anaesthesia. Headache is due to cerebrospinal leakage through the site of accidental dural puncture. Epidural blood patch is considered as the better curative treatment. Acute or long term backache is often reported after epidural anaesthesia. Different mechanisms are suggested: needle trauma, myotoxicity of local anaesthetic and postural problem. Large prospective randomized studies are yet necessary to clarify the role of epidural anaesthesia, the duration of symptoms and the therapeutic.
