What Causes Painful Swelling In Eyebrows After Using Tweezers?

I recently bought a new pair of tweezers and after my eyebrows started hurting I didn t notice they were not pulling the hair out at the root. It s been 5 days and I have no eyebrows left at all, they are swollen red and are extremely painful! I put warm compresses on them, neosporen & vitimun E oil. Keep my face clean and haven t worn makeup. I have a constant headache and can feel my heartbeat in my forehead. What do I do?
