Hi there, i first noticed a stuck in my throat feeling around 7 weeks ago, right behind the cricoid in lower neck, then a few days later up popped a large thyroglossyl duct cyct for which im having a CT scan with contrast next week. When the TDC first came up i was having awfull cramps in both saliva glands under my chin, under my tounge, & after 2 weeks cramps stopped, i then started getting sour sting under my tounge, when i ate foods or was about to, not just spicy/sour foods but also cheeses, bread anything would set it off. Now that has stopped im quite ill, though i caught a cold as my sinuses have been blocked for 3 weeks & feel like i have a head cold, dazed, & having chills, with pain flares through my neck, lymph node under my chin is slightly swollen bean like, i can feel another in front of my left side saliva gland(under chin/tounge), these seem to have pain flares too, i feel cold all the time, esp in the mornings. Any ideas why i feel so ill & fatiged & should i go back to my GP before the scan, im getting worried about feeling soo i ll. many thanks for any advise!
