I do have big breast (post pregnancy), so in my pregnancy I suffer from upper back pain
. But I also suffer from horrible lower back pain
, I use heating pads. One on ny tail bone when I sit and another one inside my shirt, taped lol on my lower back area!! This seems to help a lot! A nice message is helpful as well, my husband gives me a back message before going to bed, life saving!! I have had back pain since around 14 weeks, I am now 33 weeks and 2 days, the pain definitely increased!!!
