### input:
Hello,For that past 4-5 days I have been having a sensation in my throat. It feels like there is something stuck in my throat! Its scaring me because Im only two months into quitting smoking. Im 22 years old who is 200 pounds. Im only 52 so yes Im fat.Also, I have heavily smoked for about 5 years but have recently quit. I can swallow, I can breathe. But I think because Im anxious sometimes I feel that I have a hard time swallowing. Feels like a weird knot in my throat that wont go away no matter how hard i try to spit it out.I especially scared that Ill wake up from sleeping not being able to breathe. Therefore I havent slept much in the past 4-5 days. I cannot sleep, Im stressed and frustrated since Ive been feeling this whatever it is in my throat. No ear ache, no jaw ache. Im so worried that it might be throat cancer that I cannot sleep or function through out the day. I have made an appointment with the hospital, but it is not until tomorrow.

### output:

Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, in my opinion, you are mostly having obstructive sleep apnea (OSA) due to morbid obesity. Due to excess body fat, fat accumulates in neck region. This excess fat can compress airway in supine (lying down) position. So patient feels breathing difficulty in night. Possibility of throat cancer is very less at your age of 22 years. Since you are smoker, better to consult ENT doctor and get done clinical examination of throat to rule out throat cancer. If this is normal then consult sleep specialist and get done full sleep study to rule out OSA. You need to lose weight as soon as possible. You may need BiPAP support.
