Tight throat, dry cough, hoarse voice, sore throat for 6 weeks

i've been having the below symptoms for 6 weeks. Does anyone know what it could be experienced these symptoms?

tight throat hoarse voice that gets more hoarse after talking dry coughs swollen lymph node in neck throat gets sore or hurts the more I talk

My doctor doesn't seem to know. I've been through two rounds of antibiotics and they didn't help.

I experienced similar symptoms two years ago, I was diagnosed with lpr -a silent reflux. I never had symptoms lower down in the gastrointestinal tract. I also felt lump in the throat and pain on the right side of the throat.
I saw ent and had a barium swallow and panendoscopy which both showed reflux. I started taking ppi omeprazole 20mg morning and night.
It is typical for symptoms to be worse in the morning with this condition.
I was okay for 2 years and now I have started having other throat symptoms.

Hi. Thanks for replying. Do you remember how long you has the symptoms and how long it took to feel better after taking the omeprazole? Also what were your exact symptoms? Sorry for so many questions, its no one can figure this out. I may need to see an ENT doctor. I hope your current throat issues clear up soon and you get to feeling better.

I have similar symptoms as you mentioned sore throat,white tongue,terrible sounds from lower abdomen,athlete’s foot for year now.I did all blood work results came out normal .Doctor suspected it could be acid reflux.Still I am in same phase

Hey Johnette, I hope my reply is not coming in a too late. I wanted to know how your condition is and what are you doing about it or what you did to get better. I really hope you are better now

Have you looked into LPR/silent reflux? Apart from the lymph nodes, I was getting all of your symptoms. I have now reduced my acid intake of food and drink and take Gaviscon Advance before bed and things have improved significantly.
