Hip Pain... AGAIN! Ack!

My hips are killing. I think I can safely say that the cortisone injection I had (whenever it was, I think it was before Christmas) has not worked. I have no idea what the next step is, as my doctor and I had thought that the injection would do wonders for me. Perhaps it has something to do with the pregnancy, I don't know. But I am awake on and off during the night in absolute agony, and then of course when I try to roll over I get the round ligament pain. And then I am worried about sleeping on my back (being pregnant, you shouldn't) or on my right side (being pregnant, you shouldn't do that either). So all night I am rolling from side to side every 40 minutes to an hour, worrying about sleeping on my right side or back, and trying to not hurt.

Round Ligament Pain

Round Ligament Pain is one of those annoying (but usually harmless) symptoms in pregnancy that many women suffer. It generally starts in the second trimester, and it can result in sharp pains that can extend beyond the abdomen and hips into the groin.
It usually occurs when the pregnant female rolls over in bed, coughs or sneezes, standing quickly from a seat or moving suddenly.
The round ligament supports the pelvis and uterus, and during pregnancy comes under the effect of the hormones that causes the body to stretch and become more supple. When the female does something to cause the pain, the ligament contracts suddenly and the result is a sharp pulling or stretching pain, usually on both sides of the pelvis/tummy and usually only for a few seconds.
To alleviate the pain, you can lie on the sore side, and rest. If it keeps occuring, see your doctor. To prevent the pain, brace yourself if you are going to cough or sneeze, turn slowly in bed and support yourself, and you always do stretching exercises to keep the ligaments supple.
If the pain lasts longer than a few minutes and/or is accompanied by other symptoms, see your doctor.
