I have the same problem. My neck and back (lower back) and shoulder are really hurting. I suspect it is because I am breastfeeding (laying down position) every morning and night. I tried using pillows to support my back and neck but still not really effective. I don't use any pain killer or cream because I don't want it to get to my daughter. I also tried body massage but it made it worse! I have been breastfed for 10 months and intend to do so until my daughter is 1 or 2 years old. I reckon it will get worse but I don't know what to do. Can anyone recommend some solutions?
