<s>[INST] My dentist told me a few months ago that there seems to be a possible abscess with my lower molar. I don t have insurance so we were going to watch it since there wasn t any associated pain. A couple of days ago I had some pain in my lower jaw so I m going into the dentist to do a follow up xray next week. The pain is gone but tonight I noticed bruising on my neck towards the front below the area on my jaw where the pain was. The bruise is about 3 inches long about 1/2 inche wide, not solid more like a bite mark, it looks like a hicky. Is it something that can wait until morning for my dentist to check?? Thank you, Joy [/INST] Hi whereas per your symptoms it seems to my belief you are mingling two different problems, must be a chance you have abscess right down under your question tooth which will require a ROOT CANAL TREATMENT.your other problem which is a mark kind could be some insect bite or allergy, but for exact diagnosis could only be made with physical examination to rule out the possibility causing the discoloration of the skin. See a dentist soon, delay your appointment until you can bear the pain. Start with warm saline (half cup Luke warm water+ half tbs salt)rinses at night, it helps in Chat Doctor. Thanxregards </s>
