<s>[INST] I am a black 39 year old married male. I have a swollen small lump in front of my left ear near my jawbone and a knot has come up on the right side of the top of my forehead. I have had no injury and have not been in any accident. What could be causing this? [/INST] Hi, If I were your treating Doctor for this case of upper neck lump, I would come up with only two possibilities like is lymph nodes and sebaceous cysts! Please get routine TLC/DC of your blood and an FNAC test of the lump for confirmation and to relieve your concerns! Lymph nodes could be infective, tuberculosis or even lymphoma! The cysts are benign and not to worry about them but to take care not to get them infected! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
