Yes my dear, you poor thing... it does sounds like PGP as this is exactly what I felt like...Good news is you can make it better by visiting an osteo or physio but I had to relearn the way I moved in order to make it better for myself.

1-ALWAYS bend your knees when bending down, that means even to empty the dishwasher
2- DO NOT LIFT ANYTHING HEAVY
3-Try to keep your pelvis (hips) locked and don't twist, i.e if you need to turn left, turn your WHOLE body not just the top half.
4- Keep your knees closed together when getting in and out of the bed, the car, the couch.
5- You can try sleeping with a pillow in betweeen you knees, it keeps your spine and pelvis into line.

Hope it gets better for you!
