Just to help clarify some things for you...
During a root canal procedure the blood supply is cut off from the blood vessel to the tooth making the tooth non vital (dead). Although the tooth is no longer being fed nutrition via the blood it is still sitting in a live ligament and live bone. So root canaled teeth can be sensitive to temperature and/or chewing. Root canaled teeth are never healthy because they will always harbor dead nerve tissue inside of the tiny canals and eventually the bacteria spreads to the jaw, etc. So it's actually healthier for you that you had the tooth removed.
Your symptoms indicate you have an infection. It may or may not have anything to do with the infected tooth.... but it could be coming from the jaw bone where the tooth was because maybe the dentist did not remove the infected tissue and bone when he did the extraction.
It is best to consult with an oral surgeon as this is a dentist who deals with oral infections all of the time. You should bring the xray of this tooth with you to this appointment and the OS will take another xray to compare it.
If it is a bone infection, it would require immediate attention before it progresses. So this is not something that you should wait to get checked out.
Your medical doctor will not know if it is dental related and might just prescribe an antibiotic for you... but that medication alone will not cure an infection that is residing in the tooth socket. So it's best to see an oral surgeon first.
Hope this information is helpful to you. Please let us know how you are doing.
