Hi there! I'm so sorry you are not feeling your best. Anytime your body gives you a signal something is off it is best to check in with your healthcare provider. If your migraines have historically not been well controlled with typical migraine medications, I would highly recommend seeing a (new) neurologist. Botox might be a really great option for you, especially given the fact you have multiple medical concerns. I would suggest doing some research to find a different neurologist. You will always be your own best advocate, so don't be afraid to speak up if your doctor says something you disagree with -- Like "teens and their cell phones." You are young, so find a good treatment now so you can live your best life. I wish you well.
See your doctor! Could be seizures and not chills.
