Thanks for writing your query.
After reading your post, I would suggest that you should get yourself clinically examined and investigated by an ENT specialist
Upper respiratory tract
infections can result in inflammation of Eustachian tube, giving feeling of ear blockage.
Headache can be due to associated fever or it can be a sinus headache
You should get yourself investigated for :-
1. Complete Blood Count(CBC).
3. Chest Ray(PA view).
Antibiotics along with antihistamine like Cetrizine and decongestants like Pseudoephedrine
and painkiller like Ibuprofen will be helpful for relief.Paracetamol
can be taken for fever.
You should discuss with your doctor before starting any medicine.
Steam inhalation will be helpful in sinus headaches.
I hope this is helpful to you.
