<s>[INST] i had a root canal 10 days ago, and only took a few of the antibiotics, then on monday i had a fever and a small amount of blood in my mucus, i started takeing the meds again and feel better but still have a trace of blood in the mucus. do i need to go to urgent care or should i finish the meds fisrt??? [/INST] HiThanks for your query with healthcare magic, as you mentioned you have already taken antibiotics there is no need to take antibiotics again and again which is not god for general health where one can develop drug resistance.anyways coming to your problem i think you have an open canal where the food can lodge in canal leading to pain with secondary infection.I would suggest you to visit your dentist for further completion of the treatment under aseptic conditions. Fever is also 'coz of secondary infection only.blood in the saliva may be due to remnants of pulp nothing to worry but as mentioned complete the treatment if it is not done,Hope this helps you </s>
