I’ve had these symptoms for years now. Clubbing, dark circles, enlarged lymph nodes all over, weight loss, and extreme exhaustion if I don’t sleep before midnight. I’ve had a few tests but the only abnormalities are high sweat chloride of 53, elevated bilirubin around the 40 range, and a vitamin d deficiency. I’ve had a ct of my lungs which was fine, abdomen ultrasound, heart ultrasound, liver enzyme tests were fine. But I’ve noticed a rather large bump under the skin on the roof of my mouth for over a year now. It’s where the minor salivary gland would be. It feels like a cyst above my gums where it meets with the roof of my mouth. It’s difficult to see it but I can feel it there under the palate and it’s pretty big. One ent said it was an extra salivary gland and another ent said it was just an inflamed bone. I don’t believe either of them. Any information would be much appreciated
