the tenderness and sensitivity in the skin on my ribs has gotten worse 😳 it now feels like I burned it with hot water and it only feels better when I put something cold on it. my doctor said maybe it was my bra but I didn't wear one for 2 days and it still bothered me. it goes away over night and then comes back a couple hours after I wake up and it's also worse when my clothes rub on it. my next appointment isn't until the 29th and I don't want to go in for something that isn't concerning the safety of the baby. has anyone had this happen before? what was it? what did you do to get rid of it?
