you should not clean you nose like this it will abrade the mucosa of nose and will bleed...and never blow your nose..what you can do is that take normal saline nasal sprays to clean your nose...
now you have headache also ,so you must consult an ENT specialist
and get done a CT scan of nose and paranasal sinuses
to know the position of sinuses.As infection in frontal and sphenoid
sinuses present with headaches
. so that medical and if required surgical management can be done .
