Hello,
Welcome to Just Answer and thanks for your question. There is nothing to worry about. Try to relax and let your pain reliever work and it should take away the pain in your temple as well as the sinus area. If you really gave it a good bang, don't be surprised if there is a little bump or bruise there in the morning.
