I would strongly recommend purchasing a memory foam mattress. My therapist told me that would help and it did for real. I do not understand, speaking frankly, how that works, but when your body is sinking it’s like all your muscles get relaxed. Try something from this list. It’s even better if you’ll find a full set on amazon with memory foam pillow to place them and your arch so the blood will go off, the pressure won’t be so high, and you’ll feel better. That’s my personal experience, though
