<s>[INST] i have a lump to the right hand side of my Adam's apple. it has been there approx 3 weeks now, Sore to touch and about 1 fingers width in diamater. should i be concerned. i recently got a MAD mandibular advancement device fitted to help with my sleeping - could this be a swollen salivary gland?? [/INST] HI. This is most probably a swollen lymph node. There is a history of MAD. Get a 7 days course of antibiotics and anti-inflammatory medicines. IF it does not solve you may go further for investigation after consultation with your treating Doctor. </s>
