So I have been having this problem on and off since the beginning. But, recently it's becoming more frequent and more severe. I keep getting this pain that radiates from the middle/upper back to my ribs. Like it feels like someone is trying to rip my ribs out of my body. My dad said it's probably severe heart burn but tums aren't helping. I thought it was just sore from the baby growing. But, it is started feeling like its spasming. Heating pads aren't working and tylenol isn't working. I had at least 6 times it started acting up yesterday and so now my entire back and neck is in pain today. Any advice as to what to do or what it is? I'm going in on Friday for a check up anyway so I dont want to go in before then unless I really need to.
