Hi I am 6 days post op and I can am not a back sleeper at all so what has been helping is a lot of pillows. Last night was the first night I slept on my side with support from pillows but felt pain after 4hours I've heard it gets better after a month.
The gurgling in your stomach and chest is normal and yes it gets better just give it a few more days the pain will go away but the gurgling still hasn't for me. It hurts when I walk too, only on one side. It helps if you support your stomach you might look funny but if I hold the most painful spot in my lower stomach I can walk with no pain.
Hope it helps I'm still trying to learn too
