The FDA has just approved the use of Botox for the prevention of migraine headaches. Botox is given every three months as multiple injections around the head and neck to try to decrease future headache symptoms. Unfortunately, the most common adverse reactions are neck pain and headaches! Hard to imagine a treatment that causes the problem you are trying to cure! But I know people with chronic migraine headaches and they are willing to try almost anything. If you have this problem, you might want to ask your doctor about these injections.
