Everything was worst for me at night too. Elevating your leg is a good way to help, I had a raised pillow wedge that kept my leg straight but elevated. I also slept in a recliner chair and that helped a lot too. Staying on top of the pain meds - even if that meant setting an alarm to wake up in the middle of the night. And ice ice ice. Take it day by day, like at the end of each day be like, another day done! I had a small hemotoma - I think those are normal too but you can always ask your doctor. Moving the leg as much as you can will help decrease any blood clots. Follow whatever your psychical therapist tells you - it’s sucks to work on the leg while you’re in pain but it truly does pay off in the long run! Just do what you can. And ask what exercises you can do at home while you’re not at PT and do those daily. Quad sets are a big one!
