I had a root canal yesterday and was in a lot of pain all day. Woke up this morning and it was not as painful. But this afternoon I started vomiting and cant keep anything down and I have a headache.. Could this be from stress for yesterday or from the medicine? Or from the infection from my tooth?
Hi, than for your query. Root canal will not cause any headache or vomiting. Check for your medicines or do you have any allergy to any of the ingredients. Infection gets subsided once the treatment has been started. Hope this is helpful.
