The objective of the study is to determine the effectiveness of Spheno-Palatine (SP) ganglion block to alleviate the pain of post-dural puncture headache (PDPH).
The primary objectives of the study are to study the effectiveness of SP ganglion block in relieving post-dural puncture headache in terms of : 1. Number of subjects who get relief of pain 2. The onset time to pain relief after application of block 3. The duration of pain relief 4. The incidence of recurrence of post-dural puncture headache Secondary objectives are to: 1. Monitor any complications due to SP ganglion block 2. Measure patient satisfaction 3. Monitor any residual effects at 1 months after the SP block

Lidocaine 2% viscous (0.5ml) will be squirted on two cotton swab sticks and one will be gently inserted into each nostril, along the floor of the nose. Slight rotatory motion of the stick will be used to insert it as far as it goes with the intention to reach the nasopharyngeal wall (posterior wall of the nose). At that position the swab sticks will be left undisturbed for 5 minutes. The swabs will be taken out and this will be repeated twice more, using fresh swabs and 0.5ml of 2% lidocaine. The block would take about 30 minutes.

Pain Score at Baseline
Pain scores will be recorded at Baseline in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 15 minutes before the SP block
Pain Score 60 Minutes Post-SP Block
Pain scores will be recorded 60 minutes post-SP block in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 60 minutes
Pain Score 1 Day Post-SP Block
Patient reported pain scores will be recorded day 1 post SP block in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 1 day
Pain Score 2 Days Post-SP Block
Patient reported pain scores will be recorded day 2 post SP block in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 2 days
Pain Score 7 Days Post-SP Block
Patient reported pain scores will be recorded day 7 post SP block in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 7 days
Pain Score 30 Day Post-SP Block

Patient reported pain scores will be recorded day 30 post SP block in a sitting position. Pain scores will be quantified using the Visual analog pain (VAS) scale. The visual analog scale (VAS) is a tool widely used to measure pain. The scale range is 0-10 with 0 being no pain and 10 being severe pain.
Time frame: 30 days
Duration of Pain Relief
Patient reported how long after the SP block the patient reported pain scores that were decreased form the baseline measures. The outcome measure is measured in hours that pain relief was achieved.
Time frame: 24 hours
Number of Participants With Recurrence of Post-dural Puncture Headache
Patient reported recurrence of post dural puncture headache resulting in treatment with epidural blood patch
Time frame: 7 days
Number of Participants With Complications Due to SP Ganglion Block
Patients will be asked to report any side effects, including: allergic reaction to lidocaine, nose irritation and nose-bleed.
Time frame: 15 minutes before the SP block to 30 days post SP block
