It feels like it s swollen somewhere in the back of my throat - like I need to keep swollowing but it doesn t go away. I have had ongoing sinus problems, but at the moment there isn t any infection. I am 59 years old, 5 6 , weight 215lbs - have never smoked. I am in relatively good health only on high blood meds. Just got tested for thyriod - negative, mono - negative. You can t see anything when you look at my throad.
