Welcome to HCM
Greetings of the day
You seen to be suffering from Benign Positional Vertigo
which can be treated with Stemetil( Cinnarazine). Just deviation of Uvula
with no associated symptoms like nasal regurgitation of food or fluid can be normal. Intermittent hoarseness
of voice could be because of infection, consult a ENT (Ear,Nose, Throat) for a check up and for your re-assurance. Warm Saline gargling will help.
