My Mother Reports Having A Strange Feeling In Her Head.

My mother reports having a strange feeling in her head. She also states that she feels energy/buzzing throughout her legs. She reports feeling what she guesses to be a feeling of anxiety. Last night she could not sleep and her body was trembling. She says that she does not know how to explain that energy buzzing throughout the body, and that her mouth feels dry, and that she's not hungry or thirsty.
