Thanks for your question on Health Care Magic.
I can understand your concern.
Chest pain, throat pain and inflammatory feeling in chest is mostly seen in lower
respiratory tract infection (LRTI).
So better to get done clinical examination of respiratory system and chest
x ray.
If both are normal then no need to worry for LRTI.
Left sided chest pain with
shoulder pain can be seen in cardiac diseases also.
So also get done ecg and 2d echo.
If these are also normal then no need to worry for cardiac disease.
You are mostly having upper respiratory tract infection (URTI).
You may need antibiotics, antihistamines and anti inflammatory drugs. Since all these drugs are prescribed medicines, you need doctor 's prescription for them.
So
consult doctor and discuss all these. First diagnose yourself and then start appropriate treatment.
Hope I have solved your query. Wish you good health. Thanks.
