Feeling of dry mouth, particularly left side of my tongue and neck is common, I feel something stretching also on this part while sleeping, sometimes it pains. Consulted the best ent doctors in the city in past 2 years, they say it's only infection due to spicy/oily food and sometimes smoking & sedentary lifestyle, also there's little bulge on the left tonsil gland and little swelling on the muscles, some times rashes too, please suggest some remedy.
