Doctor can evaluate: For unusual symptoms like these, it is especially helpful for a patient to write down her symptoms on a calendar diary, recording when each symptom started, the severity and frequency of each symptom, what makes a symptom better or worse, plus the medications / foods / drinks / activities / work that the patient does. She can show the diary to her doctor at the evaluation.
