I have been treated for underactive thyroid for around 30 years. The past decade I keep experiencing what is like very severe cold symptoms on a regular basis. My body produces excess amounts of thick green slimy sticky mucous, my sinuses get blocked, I have endless nasal drip/cough and it makes me really ill for weeks at a time. It usually ends with me getting conjunctivitis then it goes again for 6 or more months. I have been to several ENT who have managed to do absolutely nothing to help. They shrug shoulders. Antibiotics, steroid sprays don't relieve it. I even had a sinus operation! I am now wondering if this can be linked to my thyroid condition and what if anything can be done to relieve it?
Many thanks
