Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of congestion or stuffed up along with head pressure seems to be due to
Sinus infection only..
A big chunk of tissue coloured mucous can be thick mucous along with blood that might be obstructing the nasal passage leading to congestion..
It can also be a polyp thatight have formed in the nasal passage and during vigorous snuffing of nose it has detached and came off..
Nothing to worry as it will lead to opening up of the nasal.passage and will improve the condition..
I would suggest you to do steam inhalation, saline
nasal irrigation and use a humidifier in your room..
You can also take decongestant
nasal spray containing
Xylometazoline.
In case if still there is no improvement consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like PNS View x ray of sinuses can help in diagnosis and treatment can be done accordingly..
You can be advised a course of antibiotics, anti inflammatory painkiller, Oral decongestant and
steroid nasal spray..
Hope this information helps..
Thanks and regards.
