Glad you are feeling better.
I took your advice and went back to the dentist. had an OPG xray and found that the tooth next to the one I had root canal on was the infected one. He started root canal straight away and now I can sleep at nights again. all pain is gone .. thanks for your help
You should immediately notify the dentist who did the root canal. You are describing what may be an infection around the tooth inside your jaw. Severe inflammation after a root canal is also possible but I cannot tell you which it is without an examination.
