Thank you for posting your query at DoctorSpring.com
You are suffering from sore throat, burning sensation.
since yesterday you have neck swelling(neck nodes) throat pain and mild fever,throat foreign body
sensation and you posterior pharyngeal wall congested now. Your tonsils already removed.
Most likely you are suffering form throat infection now for 2 days and burning sensation in throat for
a week may be feature of GERD only.
Now you need treatment of throat infection which you can start after consulting local ent specialist or
physician. You can start following medicines
Cap- amoxicillin 500MG two times daily for 5 days.
Tab. Levocetirizine 5mg once in night for 5days.
GERD can be treated with nexium and lifestyle changes.
These symptoms does not match with any cancer or malignancy so you needn't worry about it.
Once this episode of throat infection improves an endoscopy of throat and larynx can be done by ent
specialist to confirm GERD and it will rule out other posibilites.
Hope this helps
