Hi. Can understand your concern. As per your complaint pain in a root canal treated tooth is due to infection below the root tips of the tooth. When the infection is mild there is some amount of pain and the bodies immunity plays its role to wall off the infection and cure. When the infection increases there is Abscess formation below the root tips of tooth and when there is no escape way for pus it creates pressure on the nerve fibers in the region and causes pain. Pain rising during lying done to sleep indicates that there is pus formation which causes more pressure while lying done causing increased painHeadache can be due to radiating pain from tooth and to cure it treatment of tooth has to be done. I would suggest you to consult a dentist and get an x-ray done to check for the level of infection. In case if there is abscess formation a 10 days course of antibiotics like Augmenting 625 mg twice daily and painkiller like Ibuprofen twice daily along with Pantoprazole 40 mg empty stomach in morning can relieve. But in case if there is no relief and the symptoms of pain aggravates or swelling occurs you need to get the root canal treated repeated, or the tooth needs to be extracted.
