Many things cause headaches. There are tension headaches, stress headaches and migraines. Some people suffer from Occipital Neuralgia which unfortunately medicine doesn't even touch. Many doctors claim it is incurable and not many things give headache relief. But there are things you can do to relieve the pain, even if the headache relief is just for a little while.
An unknown remedy for headache relief many don't know about is putting your hands and feet in warm/hot water. You put your head to your knees then put a bag of frozen peas at the base of your skull. The hot water on your extremities pulls the blood from your head which releases some or all of your headache.
For some this may not work due to the face everyone is different. But it is definitely something to try when you lose all hope. Next time you have a headache, give this a try. You may be surprised at how fast you get headache relief.
