Congragulations mama to be!!!! I'm having the same problem and I'm like 32 weeks! lol....my Dr suggested putting cold cabbage leaves into my bra...I admit I havent tried this yet...something about putting food into my bra lol...but I try to massage them a couple of times a day and that helps a LITTLE bit....sorry I couldnt be more help
I'm sorry honey. I've been going through the same thing. (I'm 6 weeks along) The only answers I could find were "buy a more supportive bra." Ha! I do find that the warm water in the shower helps. Maybe try a heating pad on low, or if you have one of those heatable bean bags, heat that up and put it on the sore areas? Good luck!
