Hello everyone. I want to ask, who has had sciatica? I have pain in my coccyx. I don't know if it's sciatica or a physiological norm. The gynecologist said that next week she will schedule an ultrasound. So, what symptoms do you experience with sciatica, how dangerous is it? Is it normal if your tailbone hurts?
