hello and welcome to HCM,
I do understand your concern about cancer and it is good that you know the risk.
At this stage a swelling of the vallate pappillae does not have any significance other than the fact that you may have a respiratory or throat infection
You may take a course of antibiotic such as amoxycillin-clavulanate
combination 625 mg twice daily after food for five days along with pantoprazole
40 mg twice daily before food for two weeks and an anti histamine
like levocetrizine 5mg once daily for ten days after food. Your doctor will know about these drugs.
All these will cure your problems temporarily. If you still have the blocked or odd sensation in the throat then you may need to consult and ENT and get an upper GI endoscopy
Needless to say that you need to initially reduce and finally stop smoking
Also avoid oily, spicy and high flavored food
Also do not strain when you speak.
Your ear pain will also subside with the above medication in a day or two but if it does persist consult an ENT.
take care and get well soon
Dr Sriram Nathan
