Welcome to Healing Well. So sorry to hear about what you have been going through. Have you seen a Doc about this? If so what do they say? You say the pain is stabbing, do you get any other symptoms such as a red, watery or droopy eye? Does the pain make you want to lay down or does it make you restless?
Sorry to ask so many questions just trying to build up a picture of what you are going through. Sounds like you need to see a Neurologist, preferably one who is a Headache Specialist!
