Hello.
Thank you for your query at DoctorSpring.com.

I have gone through your history in detail.
You seem to have chronic tonsillitis. The protected intercourse seems to be unrelated because it was protected and the STDs which can cause a throat infection are not transmitted through protected intercourse.

Chronic tonsillitis is sort of a vicious cycle where a previously infected tonsil which is scarred and enlarged is prone to catch infections repeatedly. These infections can be bacterial, which respond to antibiotics or viral which do not.

In addition to this, certain anatomical features like a deviated nasal septum (DNS) can predispose to chronic sinusitis and pharyngitis/tonsillitis. The deviated septum may cause inadequate draining of the sinuses by blocking the sinus opening. The congested sinuses can in turn get repeatedly infected. The post nasal drip that occurs in sinusitis can irritate the throat and result in pharyngitis/tonsillitis.
The inflammation can spread from the back of the throat to involve the eustachian tube causing the ear block and popping, and the gums causing redness etc.

The good thing is, after a thorough ENT evaluation, and appropriate treatment which may involve surgery (Chronic tonsillitis is an indication for tonsillectomy), you will find good relief. If a DNS and sinus involvement has been found, this too has to be treated simultaneously.

So in summary, if tonsils are repeatedly getting infected, it is best to have them removed. And if other factors such as DNS are present, they have to be corrected as well. I know you have been to many ENT specialists, but please do consult a good one again and proceed further.

Meanwhile, you should do warm saline gargling 3-4 times daily, after every meal perhaps.
Please take steam inhalation, 2-3 times daily. This will relieve congestion including that of the sinuses and provide relief from the blocked/popping ears etc.
An OTC like Ibuprofen 400 mg, can be taken twice a day with food, for 3-5 days. This will reduce inflammation as well as the discomfort or pain.

I hope this was helpful. Free to ask queries.

Thank you.
