<s>[INST] 31 year old female on day two of strange dull pain/tightness on the left front side of my neck. Tender to the touch. No major bumps that I can feel, no sore throat, no trauma. Pain extends from below left side of my chin down to collar bone. Should I be concerned. [/INST] Hello,I can understand your concern. Pain in only one side of chin can occur if any of the lower front tooth on the left side is infected. Sometimes infections in front teeth are not in the form of decay but if you have injured the tooth many years ago, it may remain symptomless for many years but keeps developing cyst within bone surround tooth which presents as pain at any point of time. Even if you have had injured the tooth and made it nonvital when you were kid, you can have pain now. This pain can be referred to collar bone as the nerve supply of both areas is same.As you are not having sore throat or any lymph node swelling, I would advise you to visit a dentist for examination of the lower left front teeth along with an x-ray (IOPA) of the tooth. If you are in pain, you can take Ibuprofen 400 mg or Ketorolac 10 mg when needed to maximum of 3 tablets per day.I hope this information helps you. Thank you for choosing HealthcareMagic. I wish you feel better soon.Best,Dr. Viraj Shah </s>
