I started getting these headaches in April. I thought someone had shot me in the temple with a taser gun the first time I got one. I started taking Advil every 4-5 hours and it didn't totally get rid of them but kept them more under control.
I consulted with a Chiropractor who practiced Homeopathy. She suggested I try Ignatia amara, 200 ck is the dosage. I took 3 under my tongue then 2-3 hours later another 3. The next day I did the same thing and they have resolved. The thing about homeopathy is you don't take it long term. If you try this and it doesn't work after two days it's not the right formula for you.
You can get it at Whole Foods, Jimbos and other alternative markets. It's about 12 dollars. The best money I ever spent
I hope this helps others. These headaches are miserable.
