114 INTRODUCTION Pain is the most common cause of consultation with a doctor and headache is the most common type of pain in patients with chronic pain that has no specific age range and can affect children to adults. A classification system that has been explained by the International Headache Society, classifies headaches into two Primary and Secondary groups: Primary headaches have symptoms of head pain and is a disorder alone. While secondary headaches are caused by a disorder such as trauma, infection, etc. that treatment removes the underlying cause (Harrison, 2008). The most common types of primary headaches include migraine and tension-type headaches.

Methods: In this study, totally 36 patients were studied. From each type of headaches, 18 patients were randomly selected for the study and patients of both treatment groups of tension and migraine headache were divided into three categories (6 people). The frst group was only subjected to the same standard drug treatment, the second group was subjected to the same drug treatment associated with hypnotherapy and the third group underwent only hypnotherapy. Considered checklists were frst completed providing a full description by the patient monitored by the researcher. Hypnotherapy was conducted in fve sessions spaced two weeks. Also, in categories one and two of each group, the same standard drug treatment was continued. Then checklists were completed again by patients and obtained results were analyzed. Findings: Before starting the treatment for the group treated with standard drugs associated with hypnotherapy, 69.2% of patients had severe headache and 30.8% had moderate headaches; however, after the end of treatment, only 7.7% had severe headache and 61.5% had a mild headache. In the drug treatment group, the proportion of patients was reduced from 58.3% of patients with severe headache and 41.7% of patients with moderate headache, to 50% moderate headache and 50 % mild headache, respectively. In the hypnotherapy group, 63.6% severe headache and 36.4% moderate headache were declined to 45.5% moderate and 54.5% mild headache, respectively. Comparing both types of headaches indicated that hypnosis had a signifcant efect on reducing the number of attacks and the work disability amount, that in the meantime, it had a signifcant decline in the group subjected to the standard drug therapy with hypnosis. Conclusion: This study showed that hypnotherapy can be appropriately efective as drug therapy.
