What could my right upper quaduant pain be caused by?

Im a 27 yo female with RUQ pain that has lasted for 6 months. I have no previous medical history and no allergies. I am not taking any medications.

Sounds like it could be your Gall Bladder, as you say after eating fatty foods. You do not need stones for it to be that. Also if this pain is severe sudden attack but is not a dull continual one, then I have that every once in a while and was told it is a floating rib or something to that effect and when your turn it pinches an organ and hurts then the pain goes away in a few minutes.

Dry mouth and sour tasting saliva?

For the past two months i’ve had this nast sour tasting saliva that i cant get rid of. This is also causing semi bad breath and white lips that form white crust on the sides of my lips. it gets a little better if eat something but then it comes back! i hate it, i put chapstick on but it only helps for a little bit. i drink lots of water but it doesnt seem to really help! its so annoying because i have this nasty feeling in my mouth as if i hadnt eaten anything or brushed my teeth. by the way i am NOT pregnant and i do not have any acid reflux symptoms. Also, my stomach occasionally feels queezy.

having bad breath have many possible causes. bad breath causes may include bad bacteria, dirty mouth, dry mouth, gum disease, medications, stomach-related illness, cavities, eating a garlicky meal and lack of oral hygiene. bear in mind that bad breath treatments depend on the cause of bad breath. but remember that one best solution is a good and proper oral hygiene. make sure that you keep the mouth well hydrated by drinking lots of water. visit a physician if bad breath cause is not in the mouth for it may signal other illness. for more tips about bad breath visit http://www.oramd.co.uk
