Constant moderate to severe pain at 26 weeks

Deanna

I get these unrelenting contractions that come in waves every 30sec and last up to 2min each and this goes on for up to 3h.... I'm in horrid pain so bad I cant hold back from screaming a lot of the time during. I'm not dilated at ALL and they arent full belly contractions, hydrated and fed well, Im up and about until I'm in agony because i have a toddler and dad doesnt do much, I think they are just braxton hicks but I've never heard of them being this painful or timing being like this. Has anyone had this problem? What the hell is making it so painful and is there a way to deal with how painful and frequent they are? How am I supposed to give birth like this with no painkillers? (I'm allergic to what they allow) I'm having a full on panic attack here I cant find anything about what I'm going through
