Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain bright red areas over the soft palate along with severe cold and
sinus infection seems to be due to inflammation in the throat and does not seems to be due to
fungal infection, therefore
anti-fungal medication like Nystatin will not help..
I would suggest you to consult an Otolaryngologist and get evaluated and a throat swab culture can help in confirming the exact cause of infection..
You can be advised to take a course of antibiotics like
Azithromycin, anti inflammatory painkiller like Motrin, decongestants like
Phenylephrine, mucolytics like Ambroxol..
You should do warm saline gargles and steam inhalations..
Avoid spicy and chilled foods and drink plenty of warm water..
Suck throat lozenges..
Hope this information helps..
Thanks and regards.
