Hello Over The Past Few Weeks I Have Been Experiencing

Hello over the past few weeks I have been experiencing increasingly painful pubic bone pain. The pain feels like it's on the outside if that doesn't sound weird. Its activated by walking and when i go into a sitting position I get a sharp pain that starts in the center and radiates out towards my hip joints. I also get this sharp radiating pain while changing positions in bed, get in and out of my truck and if i try and pick something up off floor. At times it actually feels like something is separating. I am a med nurse on a 45 bed rehab unit so my days are spent on my feet walking after a long day I have extreme pain in my pubic bone when trying to stand which makes it VERY difficult to walk once I've been sitting and hard for me to straighten out all the way. I've spoke to my obgyn about this and he suggested the mommy band which I've been using but it doesn't seem to be helping. He now is suggestions physical therapy but I feel like this will make things worse. So I'm hoping someone else can shed some light on the pain I've been feeling.
