pain 2 years after pelvic fracture

I'm an 18 year old girl and 2 years ago I fractured my pelvis in five places in a snowmobile accident. When I walk or do anything my hips make a popping/clicking/ crunching sound and it can be painful. Sometimes it feels like somethings pinched also, especially when I wake up and it can be extremely painful. It sounds and feels like the bones are grinding together. I almost always need help when getting up off the floor, and sometimes have trouble supporting weight and climbing stairs. Driving more than thirty minutes can become painful, and my hip (mainly my right one though there were fractures on both sides) becomes painful and sore to the point where I'll actually have to pull over for awhile. My hips will frequently cramp up out of nowhere. If I sleep on either side for too long with even slight pressure on either hip it will cause a lot of pain. after the accident I was brought to the hospital (I also had a pretty bad concussion). I was kept overnight because of the concussion and in the morning they let me go home and told me I could walk, they didn't recommend a walker or crutches or anything. The pain is interfering with my job sports and life in general. Is there anything I can do about this?
