hi I had the same problems. I got this breastfeeding pillow available at any baby stores. I got one from babyoye. it was a lifesaver. do check it out. and try hot compress for your pain.

Please do ensure that you are taking your Prenatal vitamins. Also check your posture especially while breastfeeding. It's fine to start with some back strengthening exercises now and you can visit a counselor for the same. You should be able to find someone close to.yoir home thru this app.
