Sorry to hear about the facial twitching but I must agree with JW. You should call your doctor to report what you're experiencing so they can note it in your file and ask them if they can call out a prescription for you.
I called my neurotologist immediately after my first go round with what I believe were hemifacial spasms (doctor internet), he called out a Medrol 4mg pack which I started today. Medrol is also a type of steroid. I've spoken with the doctor's office every day, they are concerned about this.
I picked the prescription up last Friday, it took me till today, Wednesday, to get up the nerve to take it but I think it's helping, I don't feel like something is "crawling" along the nerves under my skin on my face. What convinced me was my daughter gets Botox injections, she explained to the NP what I was experiencing, the NP explained fully to my daughter what was going on & strongly encouraged her to convince me to take the steroids. So after talking to many friends, family, doctors, and the pharmacists I'm almost through day one of a six day regime. Medrol pack is like a Z pack if your familiar with that antibiotic. As a side note, it was a cheap prescription as prescriptions go.
Good luck with this, will keep you in my thoughts & prayers.
