My 9 year old has been complaining of being in physical pain for over a month. Her color is continually visibly pale with sunken eyes. She complains of chronic muscle fatigue and pain in her limbs and in her sides. her mood and affect have changed and she is not engaging in activities. She continually sighs and complains of being hot and overheated. She has no temp. The neurologist has diagnosed her with Metabolic Myopathy. I believe this can be the cause but am not convinced that this is all that is going on. Not sure where to go or what to do to further investigate.
