Hi, i had the coccyx damaged when I gave birth to my son years ago. I could bearely stand up or sit down at that time. My doctor told me I had to wait some time and it will heal. three weeks ago, I started to train on a new elliptical , also I started doing some lipo-cavitation. I have had about 4 sessions. when I had my periods about 10 days ago, I had severe pain in my pelvis (especially the coccyx), going through my right leg. I would like to know what caused the pain, and also, what I should do to prevent any more damage to my coccyx. Thank you.
