<s>[INST] I have a small, hard lump on the left side of my Adams apple (thyroid?). I have no other disturbing symptoms (pain, difficulty breathing or swallowing, weight loss, sweating), but my vein right below my jaw on the left side feels tighter than the one on the right. I noticed this about 1,5 weeks ago, any reason to be worried? [/INST] Hi! Good morning. I am Chat Doctor answering your query. If I were your doctor, with a hard lump I would at the earliest refer you to either a ENT specialist or a general surgeon for a clinical examination and related investigations like a thyroid function test, an ultrasound of the thyroid and neck region, and an FNAC of the hard lump. Further management would depend on the results of physical examination and reports of the investigations. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor. </s>
