Hi! My name is (…) I’m a female and 18 I’m 5’5 and 145lbs. As I know of I don’t have any medical problems except migraines that I am on medication for and have been for almost a year. Just these past months randomly I’ve felt nauseous, constipated, dry mouth, dizziness, light headed, headache, tunnel vision, weakness, shortness of breath, randomly extremely hot and then randomly extremely cold. This week it has been like this everyday and seems to get worse each day! Any ideas what it could be?
