Thanks for posting your query..
From the symptoms you are having, it could be a evolving Bell's palsy
of rt side..
The features will be -
inability close the eye fully and forcibly keep it shut..
deviation of mouth to the other side
absence of wrinkles
and forehead furrows on the affected side
inability to blow air tingling sensation
over the affected area..
All features may be present or may not be..
The nasal spray
you are using is unlikely to cause this..
Consult your physician once for proper treatment..
Take care.. I will be available for further queries..
