Chiropractor that is Webster certified! Also if you look on YouTube there is free pregnancy workout videos by a lady named Jessica her Chanel is Pregnancy and Postpartum TV and she has workouts and yoga videos that helped me with my sciatica pain. I also bought a massage gun to target the area as well.
Osteo. She worked on the area and gave me some exercises to open the space. What also REALLY helps is my husband opening my lower hips by pressing inward at the higher part of my hips. Often the lower part is pinching the nerve so that opens up space. Similar to that type of counter pressure in labour to open up the bottom part of your pelvis
I found monthly massage and in between chiro visits helped with it my last two pregnancies. I’m experiencing again and need to book in. Hoping g you can find some relief!
