Hi dear I'm sorry to hear you're still in pain. It sounds like sciatica and I had that during pregnancy. The shooting pain went away right after delivery. I did have it pre preg too but it's not all the time. I'm not sure how long you are post partum, but perhaps your uterus has not gone back to its original size and it's still pressing on the sciatic nerve. I know the pain can be really frustrating and affects your day to day. I'm not sure if seeing a doctor or chiropractic practitioner / osteopath might be helpful in your case if the pain still persists. For me the most useful pain management was to do yoga regularly that focuses on the hips and get deep tissue massage on affected area. Hang in there, hope you feel better soon!
I totally recovered after 3 months
