I need some input. I am 37 weeks pg, and have BAD sciatic nerve pain. I can't sleep, it hurts when I sit, stand lay down, ALL THE TIME. I wanted some quick relief of the pain. Which would be better a Chiropractor or a Physiotherapist??? I have appointments booked with both for tomorrow, so I need to cancel one of the appts. Which one is better for fast effective pain relief, and safe.
