My daughter went to the doc and they said that she had a post nasal drip and the start of sianitis (sp?) so they put her on the z pack the day after they saw her due to the severe headaches she was having. She has said the pain is behind her eye sockets and around the back of her head where she cant lay down on it. I have given her ibuprofen (2 200 mg) and extra strength tylenol (2 500 mg) and neither help. She took a naproxen (220 mg) but it upsets her stomach so she cannot take them anymore. Could this just be from the sinus build up and what can relieve her pain??
