Blood patch for spinal headache. A recurrence and a complication.

The management of a patient is described who has a blood patch for spinal headache, but who had a recurrence of symptoms 1 day later which was successfully treated by a second patch. A second case is described in which there was a second dural puncture immediately prior to the blood patch and, immediately following the blood patch, the patient complained of severe debilitating 'paralysing' pain in both legs. This pain was of short duration and the blood patch was successful. Some further observations on the use of a blood patch are recorded.
