Yes, this is so common with anxiety, all your muscles are tight, and the muscles in your forehead are no different. It is a very uncomfortable feeling, but, I assure you, as you calm down, so will the feeling.
Try putting a hot cloth on your forehead, this might help to relax the muscles, I know when I sit is a hot bath, my muscles relax, I hate to get out.
