Suggest Remedy For Chronic Headaches And Migraines

Hi I have had chronic daily headaches/migraines 24/7 for many years but now it is getting unbearable. This one was getting worse over three days and I was in bed yesterday wanting a huge dose of morphine to stop the pain which was all over my head. I take Imigran which eventually worked last evening. I have had a CT scan and the doc says the scan is normal. What do you think of botox injections for head pain?
