The above answer to your query is absolutely true. But the main cause is your sinusitis
. As the secretions are getting collected in the sinuses there is heaviness in the head also feeling dizzy. You need to take steam inhalations, drink plenty of warm water as well try taking mucolytic
(such as Ambroxyl/ Bromhexine
) along with sudafed
and saline nasal drops. Drink plenty of water so that it keeps your nasal mucosa hydrated. Any more doubts you are welcome. If the symptoms does not subside with in 3-4days you need to take antibiotics.
