Flower, congratulations
I'm sorry for the extra pain. Were you able to talk to the anaesthesiologist or your doctor afterwards about
it? I think it's important to talk to your doc about
some imaging - epidurals can cause things like haematoma in the spinal canal which can be picked up on CT or MRI. You can also get stretching of the nerves (apologies - my obstetrics knowledge is mostly cow related...) that I'd guess would cause similar symptoms too.
Whatever is going on, I hope that it resolves soon.
Laura
