I have got an uncomfortable lump inside my chin towards the left side. (Submandibular triangle) Started noticing yesterday. I had quit smoking but started again yday. Also trying out a meal replacement protien-nutrient shake for breakfast and often dinner. (For weight loss). The lump can't be seen directly. But how hurts if I press it. Also got a slight discomfort in the ear. (Left ear itself). Also had excess alcohol last day.
