hello and welcome to HCM,
Two weeks is a long time to suffer and you should not suffer more!
Do the following:
1. A complete examination of the ear, nose and throat
2. Audiological examination including PTA and impedance to delineate your cause of ear fullness
3. Imaging study such as CT of the sinuses
and Temporal bone
to give a permanent solution to your problem
the further course of treatment will be determined by the test results
But do not panic which is probably why your heart is racing so much!
Get well soon and bet back with the reports
Dr Sriram Nathan
