Wierd skin thing post op

I am now 10 days post op and this started shortly after surgery so I don't believe it's related to any weight loss. When I sleep at night , it's always on my side and for 3-4 hours at a time before I turn over. THe skin/muscle on the side of my hip becomes so numb it's painful. I slept in same position before surgery and had no problems, now by morning both sides of my hips are so sore and numb in the morning it's a pain.

Weird!  I recommend calling your surgeon and asking.
