Hi there
You have exactly what i have suffered from for 2 years on and off. I used to get sharp stabbing pains on the left handside above my ears, mainly left side, ocassionally right. This has lessone significantly over time. I can confidently say to you to go and see a physio therapist. I actually finally did this and found out that it was all assocated with my spine and was experiencing cervical headaches. So i have to watch my posture, strength my neck muscles and shoulder muscles. This could possibly be what is happening with you. Well worth a try.
Linda
