Thanks for writing to H.C.M. for your query.
I have gone through your query and as you said that you have cold, pain on your rib cage
and your ear is also having pain, your pain is extending to your left shoulder and neck.
On considering your complaints it is clear that you are suffering from ACUTE RESPIRATORY TRACT
INFECTION WITH ACUTE OTITIS MEDIA
, since you are complaining of pain over your rib cage also therefore we should rule out pnumonia as well.
To manage it you should take -
(a) Antibiotic- As per recomondation by culture and sensitivity report.
(b) Anti inflammatory.
(d) Steam inhalation.
I hope this will help you, failing it, it will be better to consult your physician.
