I’m not familiar with the side effects of the procedure but do know that steroids alone can seriously effect ones sleep, even though your sister is on a taper of the dosage. Some people find sleeping medications helpful to counter this problem. I know others here have had the procedure and am sure will let you know their experiences.
Welcome! I think you’ll find this to be a wonderfully supportive group of people who are always willing to share their knowledge and experiences. I’ve certainly found that to be the case.
Wishing all the best to your sister and much success with the treatment!
