Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain generalized pain in upper gums on right side along with swelling on face and stuffed up
nostril seems to be most probably due to infection in maxillary sinus on the right side..
Due to inflammation and infection there is accumulation of infectious fluid in the nose leading to congestion..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and x rays like PNS view or
MRI of the
sinuses can help in confirming the cause and treatment can be done accordingly..
As of now continue taking the medication that you are taking to relieve pain, along with it do steam inhalations,saline nasal sprays,
steroid sprays and decongestants like Pseudoephadrine..
Hope this information helps..
Thanks and regards.
