After I had surgery almost two years ago I ended up in ER six times with in six months from paralyzing migraines due to my thyroid hormone being off . The conclusion was I have hashimotos disease , which is common when you have had one autoimmune disease you are susceptible to others . Cushings is gone , yes. Today I’m cautious about eating gluten , eating too much sugar , eating animal products aka cholesterol and I keep a close eye on my hormonal Lab work . Occasionally I still do good migraines when I do this essential oil is a savior.
