I've had it on and off since 12 weeks. At my worst point I was even on crutches. My GP referred me to physio, but in all honesty, they are telling you the truth - there really is nothing you can do about it til after the baby's born. The relaxin hormone makes all your muscles relax so if your sciatic nerve gets pinched in the process, that's pretty much it til your hormones go back to normal after birth. My GP also told me that unfortunately it can take up to 12 weeks to go away completely after birth. Sorry to be the bearer of bad news, but I know exactly how you feel.
