Hi, I've Suffered From Migraines For 6 Years Now, I

Hi, I've suffered from migraines for 6 years now, I started getting treated for it about 2 years ago. Everything was find until a few months ago where I started getting sharp, shooting pains on my left temple. They only lasted about 15-20 minutes. Then I started to get a stronger pain similar to that behind my left ear. Now I get an even stronger pain from my left temple to the back of my ear. It's so strong I just drop everything, put pressure on it and curl up regardless of where I am. Its a completely different pain from a migraine. What should I do? Any advice?
