think you can raise it to ur gyne they should have something for you. I waited till I give birth then I buy the cream from a medical Hall to apply and it works for me. though I cant really sit well throughout my pregnancy and anyway my back has been more painful than this so it didn't borther me as much.
Hey there! have you already consulted your doc? Is gynae giving the green light for the op? How painful is it? Are you willing to tolerate the pain for another 3-4 months?
