I am having the most excruciating pains shooting down my butt cheek and leg. The midwife says its probably sciatica and should clear up by its self but right now that is no consolation to me as i have spent most of today and nearly all day yesterday laying down either in tears or close to tears. Please please someone tell me how long is this likely to last and how can i shift or numb the pain. Im 33 wks gone and don t think i could bear it if i had to spend the next 7wks like this. Any advice will be very welcome. Thanks x
