I have been taking Synthroid for years and it doesn’t make them better or worse. And I was surprised to learn about the problems with birth control pills and migraines. I stop taking them and that helped.
Get your ears double checked. Sometimes you have an inner ear infection that is behind the wax. They shouldn’t be red and sore several days later.
You can test for sciatic by the pressure points at the top of your leg. If it relieves the pain, that is it. Again, a doctor visit is needed to check for you.
Take care and follow-up with your doctors.
