Hello i have noted your problems in detail. .
Since your also having dry nose and pain inside nose want to know whether its a acute or chronic problem. .
Since its dry your nasal mucosa is nore prone for injury
and infection which can cause pain. .
Now wats the reason for dryness needs to be evaluated by ENT specialist
, if the problem is for long duration conditions like atrophic rhinitis
should be ruled...Treatment for your problem lues in treating the cause, symptonatic treatment is not the solution wat I feel. .
Any queries please let me know. .ll try to answer them
