Sore throat : Tough one to answer. Certainly the pennicilin should not, of itself, cause sore throat. It could very well be a coincidence. It could be some other irritant from the procedure as well.

Probably n ot: Root canal infections do not cause sore throats. You may have caught a cold during the past few days.
Dr. Stephen Shpeen

Sore Throat: Your sore throat and gereal malaise has nothing to to with your root canal treatment. However if you start an antibiotic regimen you should finnish it. Although most sore throats are a viral infection where an antibiotic like penicillen would not be effective to treat it . So your sore throat is not a result from your root canal treatment. So see a physician.

Coincidence: Antibiotics must be taken in a 5-7 days period in order to be effective. Taking it before rc only is not recommended. You may have a cold related to your throat. You may visit ur doctor.

Can be a big problem: Severe headaches, accompanied by neck pain, could be a type of meningitis (serious infection around the spinal cord and/or brain), although the real flu can cause similar symptoms. Cold feet, chills, and tremors occur when fever is rising; sweating happens when fever is dropping. Light-headedness and vomiting make it all more worrisome. A trip to the doctor is needed to evaluate these symptoms.
