Question about painful BH

Shelby
I've been having Braxton hicks since 18 weeks. I'm now 23 weeks and my muscles in my back are sore from them. I know if there's more than ten an hour you should call your doctor, but last night I had ten less than 5 minutes apart, but then they stopped. I don't go through the day without feeling them, but they're just so uncomfortable and painful. If it's to the point where I'm sore should I be worried? This is my second pregnancy and I never had any that I could feel with my first.
