Hi doc,today when i bent over i had bright yellow liquid (watery) come out of my right nostril for two times , like 2 two table spoons of each time.Since then i m feeling very weak and i tried googling this, but i couldnt find anything on it. i did find one article that described something like it, and she said her doctor told her it might be brain fluid, so i m kinda scared. she also said it might be because of allergies. but i m not allergic to anything...that i know of.
