You are right. You seem to have Chronic Sinusitis
When you lie down at night the infective pus from sinus drips into throat and causes infection in throat and tonsils causing Pharyngitis
Bleeding from nostril may have occurred because of redness in nose (congestion) because of sinusitis and rhinitis.
You may start an antibiotic (third generation Cephalosporin( with decongestant nasal drops (xylometazoline
). Steam Inhalation in a very good decongestant. Gargling with hot water and salt is also very useful.
