Confused are braxton hicks painful or not?!!

Corinne
I have to rant because I read so many posts about Braxton hicks. I'm 33 weeks nearly 34, I'm not sure if I have had them or not, but I keep hearing " braxton hicks are so uncomfortable and causing agony" then I hear " braxton hicks shouldn't be painful".......... Can I just assume that braxton hicks are different for everyone, as there is no definite common symptom
