Just to know how long these symptoms have been existing? You are having a flu syndrome which could be caused by sinusitis
or rhinitis or cerebrospinal fluid
discharge. In any of the cases, consultation with an ENT specialist
will be of added advantage. If cerebrospinal fluid discharge then a neurosurgeon will be the one to assist you.
First of, if you are having flu syndrome, then you can give a couple of days so that they symptoms to disappear. An antihistamines such as pheniramine
or mequitazine or chlopheniramine etc, if symtoms have lasted for more than 5-7 days, associating an antibiotics such as amoxicillin
could be of additional benefit. Steroid spray may help if you feel like you are having a nasal irritation or blockage or congestion.
Hope this helps!!
