I have a tooth abscess and have a sinus infection which may or may not be related but it is making me miserable. I have a throbbing headache and the pressure in my sinus cavities is making my tooth pain almost unbearable. I took a 24 hour claritin for allergies this morning but think I will start taking some avelox until both my absess and sinus infection clear up. From everything I'm reading about avelox it sounds like the medicine I need. Are my symptoms something that this Avelox should take care of?
