Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you are suffering from a condition known as Globus Pharyngeus in which there is a continuous feeling of something stuck in throat..
As you are a smoker it can be a cause for the symptoms as
smoking is considered to be a symptom responsible for globus sensation in throat..
It is generally not related to caner..
I would suggest you to consult an ENT expert and get evaluated and he can also advise investigations like chest x ray,
endoscopy, barium swallow, oesophageal manometry etc..
You should quit smoking as it can help in relieving the symptoms..
You can be advised symptomatic treatment as per the cause like antacids and
omeprazole for
acid reflux while if it is due to stress anti
anxiety medications and behavioural coagntive therapy can help..
Hope this information helps..
Thanks and regards.
