I have had sciatic pain for the last 4 months. Had an MRI done and it show bulging disk 2 in the lumbar and 1 in the sacrum. I have been doing private yoga (one on one) and the exercises in the basic back book, but its not getting better. I have an appointment with a pain management doctor next week (after 3 month wait). What will they do for me there? Do you think I will need surgery?
