Hello
I am Dr Ravinder sharma . ENT sorgeon
On the basis of the information provided It appears the problem lies in nose, sinuse sor chest causing these symptoms. It will be appropriate to go for
X ray PNS and X ray Chest to look for the cause of your symptoms. Pneomonia is one possible diagnosis to cause similar symproms however there are other possibilities too.
I hope this answers your concern. Feel free to contact me if you require more information about it
with regards
