Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that throbbing veins on temple can be due to cold and sinus congestion and can be commonly seen during cold and cough..
You need not to worry and can take anti-inflammatory painkillers like Ibuprofen or Naproxen for relief from pain..
Take steam inhalation and appropriate rest..
As Benlyn mucous cough night contains
Diphenhydramine thatbis anti histamine and
Guaifenesin that is a cough expectorant, you can continue taking the same and along with it you can take decongestant like
Phenylephrine, mucolytics like Ambroxol..
Do warm saline gargles and chew a Vitamin C pellet.
Avoid chilled and spicy food and sip on plenty of warm water..
You can take decongestant
nasal spray containing
Xylometazoline..
Take soft diet..
In case of no improvement consult an Otolaryngologist and get evaluated..
Hope this information helps..
Thanks and regards.
