Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain soreness of
nasopharynx along with spitting up of snot mixed with blood seems to be due to infection that can be upper
respiratory tract infection,
sinus infection etc..
The brown stuff over the tongue can be
black hairy tongue and is commonly harmless condition and can occur due to overgrowth of tongue papillae and entrapement of bacteria and fungi as well as dead cells over the tongue..
It can also be due to poor
oral hygiene, excess intake of tea and coffee, tobacco and
alcohol abuse, taking medications containing bismuth etc..
I would suggest you to consult an Otolaryngologist and get evaluated for your nasal problem and bloody snort and he can advise you to get nasal endoscopy done along with PNS View or MRI of salivary glands..
He can advise you with antibiotics ,decongestants, saline nasal irrigations and warm saline gargles..
For hairy tongue you should gargle with 1:1 solution of
hydrogen peroxide and water..
Brush your tongue with a soft toothbrush by dipping it in above solution..
Clean your tongue using a tongue scraper..
Do warm saline gargles..
Maintain a good oral hygiene..
Limit intake of tea, coffee, tobacco and alcohol..
Hope this information helps..
Thanks and regards,
Honey Nandwani Arora.
