Thanks for providing more information.
I understand your concern as you are suffering from last few weeks and it's now getting worse over the time.
Possible causes may include Sinusitis,Eustachian tube dysfunction which result in clogged ears,cough,stuffy nose.
It's good to see an ENT specialist for a clinical examination and further X-ray/CT scan of para nasal sinuses can be advised.
You shouldn't worry as your symptoms like clogged ears,congestion can be treated well.
You use a humidifier in your room.
At your current stage,ENT specialist can provide you better treatment.
Try nasal irrigation,saline gargles.
Hydrate yourself with plenty of fluids.
Get well soon.
