Hello
I understand your concern.
Hot flushes in your case may be because of stopping of drug
estradiol making menopausal symptoms getting flared up.
Also you need to get tested for blood
thyroid hormone levels as their alteration may cause hot flushes.
You may try slowly adapting your body without the external hormone supplementation by,
-Maintain adequate hydration by minimum8-10 glasses of water.
-Avoid alcohol,hot spicy food,caffeinated drinks.Increase intake of fruits and vegetables.
-Wear light loose clothing.Always stay in cool and well ventilated environment.
-Practice regular
yoga and
meditation for destressing your mind.
If symptoms persist beyond 7 days,consult with gynecologist for
hormone therapy.
Hope this information helps.
Wish you good health.
