Chiropractor who specializes in pregnancy!
Heating pads are what i use...I'm a ftmtb and had a recent back surgery. My Dr's told me heat and there is an oil out there by young living that I swear by. It's called deep relief and is all natural. It even comes in a bottle w a roller ball for easy application. I use mine b4, during and after work. It seems to help. I'll be 32 weeks Fri. Good luck!
