Thanks for writing to H.C.M. for your query.
I have gone through your query regarding cld with running nose , congestion in throat with soreness, headache, cough
and feeling of difficulty in breathing.
These all symptoms are related to respiratory tract
infection , as for as pneumonia
is concerned you have difficulty in breathing is a supportive symptom but for confirmation we need X-Ray chest in P.A. view. this X-Ray will tell about pneumonic consolidation.
So you may take now-
(a) Antibiotic- Preferably broad spectrum.
(b) Anti inflammatory and antipyretic
(d) Steam inhalation.
I hope this will help you , otherwise you should consult your phyician.
