Flaming June: Your symptoms are nonspecific to a particular condition. Start with the basics : sleep, nutrition and stress management. Hot flushes may result from hypoglycemia and low thyroid (hypothyroidism). Fatigue may be from both of these and poor sleeping (time and quality). See a caregiver who is willing to tackle the whole patient and not someone who will only test your hormones. Good luck !
