Now i have a lump under my jaw line suffer from headaches my gums are red top only and roof of mouth tender all on the leftside plus my two front teeth are starting to part [/INST] Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query you have lumps on jawline with headache which is mainly due to stone in salivary gland duct, infection in ear or tooth, enlarged lymph nodes. I would suggest you to consult dentist or ENT specialist for proper diagnosis. Doctor may prescribe X-ray, ultrasound OR CT scan to rule out other causes like lymph node or Osceola. Doctor may recommend you to suck on sugar-free lemon candy. You should be dink plenty of water. Doctor may also apple pressure on duct to expel stone. If above methods doesn't work then there will be a surgical procedure for that. If it is due to infection in particular tooth get x-ray of that tooth done and start restorative procedure accordingly. Hope your concern has been resolved. Get Well Soon. Best Wishes, </s>
