my lower gum line looks like it has a dark red line from horozontially and occasionally a hard lump keeps coming and going in the same spot its tender but doesnt really hurt but it feels like kind of like its swollen when it does appear? also about two nights ago my gums started to really get sore and caused me pain i had developted what sort seemed to be a tiny blister except that it came to a white head, i felt really flushed hot then nauseated to my stomach and i could slightly taste a leaking some kind of fluid?
Hello, As per your description it seems you are having Chat Doctor. . The blister is opening of infection from either soft tissues (gingival, periodontal ligament) or from hard tissues (bone, tooth)It has to be assessed clinically and radiographically about the origin of abscess.  Most commonly it is from carious or traumatized tooth. And to treat it permanently RCT of involved tooth is done. And blister resolves forever.if its from gums only.then gums /periodontal surgery is done.to treat it.meanwhile u can use chlorhexidine mouthwash/ gels on your gums temporarily.
