Hi.. Can understand your concern.. As per your complain in case if you have broken molars at the gum line and you have noticed discharge from them it clearly indicate that you have infection below the root tips of the teeth leading to pus formation and as the pus is getting an escape way to discharge there is no pain.. Swelling over the jaw in the region of the infected teeth can be due to accumulation of pus into the soft tissues. For relief from this you can get the root pieces extracted followed by a lower partial denture.. The other parts of body in which you are getting swellings and lumps is not associated with the teeth and you need to consult a physician to get evaluated for the cause of swellings and get treated according to the diagnosis.. Hope this information helps.. If you find the answer helpful please write a positive review and click on find this answer helpful as a token of appreciation.. Thanks and regards..
