AP - I had an epidural too. That's when some permanent damage can occur - because you're not aware of the pelvic pain and so open your legs "too" wide IYSWIM. Make sure all the staff present know you have pelvic pain and let them see how far you can open your legs before you have the epidural.
I wasn't allowed a pool either cos of previous emergency c-section - grr.
My m/ws were fantastic and never let my legs go further than the "pain free gap". some people have tied a bit of string round their knees to prevent them straining too far!
Dd is now 7.5 mths and the pain is almost completely gone - just have to be careful lifting the car seat and pushing the pram (esp with big ds on the buggy board - v heavy). Oh and not being too adventurous during sex - I've been walking like John Wayne a couple of times recently.
My physio said that because it's a hormonal thing it can take 6-12 mths to disappear completely. And it may or may not happen in another pregnancy.
Get a suport belt from the physio btw!
Don't sit with your legs crossed or cross legged on the floor.
Don't lift anything that can wait until your dp can do it - seriously. I would do one daft thing and be paying for it for the next few days
My Gp and surgery m/w weren't overly sympathetic about my pain, so I bypassed them and spoke to the m/w at the hospital at one of my appts. who referred me to a physio in the maternity unit. Once i had an "official" diagnosis then the surgery etc took me seriously. Annoying but worth it.
You might just have to pester people to get heard - but once you can give it a name people will bend over backwards to help - even if you can't (groan...)
