What causes swelling on one side of the neck?
Patient: I have a swelling on one side of my neck gland when I eat a meal.  Hopefully, I am having a CAT scan tomorrow but I would like some peace of mind for the next 24 hours.  With this problem, does it always lead to an operation?  I am going overseas in two weeks time for a five week period.  I am 63 year old woman with up till now perfect health.   I take no medication. Doctor: Hi,DEar,thanks for your query to HCM.I studied your query  in depth.1-In My opinion the swelling on one side of neck gland-thyroid, especially when you eat,is due to -Sialeadenitis with Sialolithiasis with stone in duct obstructing the submandibular gland,.2-This may need urgent surgery -as it increases with eating a meal , indicating that the swelling is due to the stone obstructing salivary duct of the submandibular gland.3-If you are going out-station-better have a -on-travel -health insurance to cover any emergency -which may need Urgent Surgery if need be.4-Hope this would solve your query.5-Wellcome for any more questions on new or this subject also...Have A Good Day..!!
