Embarrassed but kind of glad it happened

We went to our Infant care class tonight at the hospital. After the class was over hubs had some follow up questions and we were getting ready to leave but the nurse was still talking. My hip issues (previous nerve damage that has gotten worse with pregnancy) started happening while I was standing and brought tears to my eyes and I had to sit down. The nurse asked if I was having contractions and I had to tell her it wasn't that it was hip and pelvis issues. She went through that I need to really press the issue with the dr to get some muscle relaxers or something, a belly band, a peanut ball, and an exercise ball.  I told her that last night my hip actually gave out while I was walking, while crying (because the hip pain makes me cry while I'm trying to sleep every night), and I almost fell because of it.  She said this is something that the dr should be looking into for sure and to not just bring it up each time I go in, like I have been but really push it! So hubs is going to the next appointment with me...at only 33 weeks this shouldn't be this bad without getting some help from the dr. I'm so embarrassed that I started crying because of the pain but kind of glad it happened in front of a nurse who could   assess the situation while it was happening.
