Abstract
Background: Chronic headaches are very prevalent affecting a sizable number of global populations. Occipital nerve block (OCN) can help them relieve their pain and get back to their normal life. Conditions that are treated with occipital nerve blocks include: Chronic migraine, Episodic migraine, Chronic cluster headaches, Episodic cluster headaches, Tension-type headaches, Occipital neuralgia. These may include types of pain that start at the back of the head near the neck, and then radiate outward throughout the skull. Occipital nerve block is a minimally invasive intervention, inhibits or blocks the disproportionate or chronic signals that are sent to the brain, processed and perceived as headache pain, resulting in pain relief lasting up to several months. It is our humble approach to see the effectiveness of this mode of minimal intervention. Objectives: The aim was to see the effectiveness of Occipital Nerve Block in patients of Chronic headaches. Place of study: Dept of PMR, IPGME & R and SSKM Hospital, Kolkata Period of study: 1 st. September, 2017 to 31 st. August, 2018. (12 months) Study pattern: Prospective Longitudinal Outcome Study Methods: After getting Institutional Ethical Committee clearance a total number of 98 patients with Chronic headaches who did not respond with conservative management were included. Patients with other causes of headache, patients with diabetes, severe hypertension, otherwise th th th contraindicated for injections, are excluded. Occipital nerve blocks performed to patients and were evaluated initially and at the 4 , 8 , and 12 week followed up using Numeric Pain Rating Scale (NPRS). Adverse events and patient satisfaction were recorded, number of attacks pre 4wks and after intervention. Results: Statistically signicant improvement is seen in these patients treated with Occipital Nerve Block Conclusions: Occipital Nerve Block effective mode of management in patients with Chronic headaches and may be recommended to patients with moderate to severe chronic pain that has not responded to conventional treatment such as oral painkillers or lifestyle interventions.
