[|Human|] Ive had a mild pain in my left lower jaw for about a month, towards the back.  Its mild and it comes and goes but never gets any worse.  At first, it was accompanied with soreness and mild swelling under my chin and on the left side of my jaw up to the ear.  That went away after a few days but the mild on and off pain in the lower jaw, towards the back left tooth, remains.  I have no pain chewing or no direct tooth pain.  Please also note that I have had a chronic phelgm problem all winter.  No runny nose, sore throat, or cough, just nagging phelgm in the sinuses.
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint pain on left jaw along with swelling under the chin is indicative of some or the other forms of infection which can be due to:1. In case if you have wisdom tooth erupting the swelling can be due to inflammation of the gum flap over the wisdom tooth and the condition is known as PERITONITIS, and it can lead to pain in jaw radiating to ear along will swell in the lymph nodes, although submandibular lymph nodes are commonly swollen which are present below the jawline but can in few cases submental [below chin] can also be involved.2. Another reason can be infection in the tooth/teeth which must have got non-vital due to necrosis of nerves as a result of infection, but the area below the root tips may get infection due to progression from tooth and can lead to pain which can radiate to jaw, ear as well as swollen lymph nodes.3. One more reason can be infection in the submandibular salivary gland leading to pain in jaw, but it will also be evident just under the jawline. You need to consult an ORAL PHYSICIAN and get evaluated to get ruled out for the exact cause of the pain and the treatment can be planned only after knowing the final diagnosis.
