Thanks for writing to H.C.M. for your query.
I have gone through your query regarding fluid in your ear and for this you are taking antibiotic and tab prednisolone
for this and suddenly you developed feeling of tightness in chest. Yur this new symptom is not related to your disease of ear and medicines, but this is giving suspition about some problem in your heart so it will be better to consult your physician about this for thorough examination.
As far as your ear problem is concern you should take-
(b) anti inflammatory.
(c) Decongestant & mucolytic
(d) Steam inhalation.
I hope this will help you.
