Migraines are recurring headaches that typically affect only one side of the head. The pain is often described as throbbing or stabbing,and it may even affect vision adversely. In especially severe cases, the patient may also experience nausea.
The exact reasons for migraines are unknown, which makes it difficult to prescribe a proper course of treatment. However, many patients have gotten favorable results by using marijuana in small amounts. For some patients, marijuana helps reduce the pain considerably and even controls nausea.
