Hi there, thanks for the reply and additional information . It seems that you are suffering from Pharyngitis ( inflammation of pharynx / throat ) , also known as sore throat in lay terms , and this pharyngitis typically causes the tightening like feeling , that you are feeling right now.
It is quite possible that although your ear infection got treated , but throat still harbored some foreign antigen , and so the symptoms such as these appeared.
But, do not worry , as this is very common and can be treated .I am mentioning below the treatment regime that you should discuss with your doctor and get started on.
1) 1 Good antibiotic drug such as Azithromycin
or roxithromycin , to complete the full course of this antibiotic , by taking it for 5 days . Discuss the dose of the antibiotic mentioned with your doctor and accordingly let him decide the time of intake.
2) Along with antibiotic , you should also start on 1 anti inflammatory drug for pain relief such as ibuprofen and also take 1 anti histaminic drug for treating accompanying allergy such as Cetrizine , which is to be taken only once a day , preferrably at night .
So, i suggest you discuss the above mentioned regime with your doctor and get started on it , and continue these drugs for 5 days , that is complete the full course of treatment , and i am sure you will get alright .
Meanwhile , while you are on these drugs , you have to avoid oily and spicy food and cold beverages .
I wish you rapid recovery to the best of health.
