I have bad migraines and I use for pain, dimeral and they can add something to not make you sick to your stomach as well.
You can take darviset (not sure if that is the correct spelling) or vicodin ES. Pain meds effects everyone differently something that dosesn't work for you may work for someone else and vise versa so maybe call your doctor and tell them its not working. Feel better!
I think anything stronger would have to be prescribed by your doctor. If it's been a week and you're still having that much pain, you should call your doctor any way.
