PPW congestion and swelling. What to do.

I had fever and throat infection one month before. Fever gone in 2 Days. Consulted ENT for throat infection and taken Antibiotic as suggested. Felt relief from pain and itching but i had feeling of like something is stuck in throat. Since one month i feel same . Consulted 3 ENT doctors in one month had several visits. Tests done : 2 times Endoscopy and CT-Scan Neck. Both are normal . Doctors  says that no big issue ,PPW is congested and swelling . Swelling will go slowly .Taking antacids as  percribed by doctor . I am taking precautions like no Spicy food, no tea /coffee. But still it feels like something stuck in throat . 70 percent of the times it feel . Rest 30 percent it feel like normal .There is no pain, itching. No problem in swallowing . Please suggest what could be the reason and what more i need to do to get it solved. Its been  more than 30 days now and i am not getting what to do.
