can't lay on my back for long periods of time as my oxygen flow feels cut in half and this belly makes my back hurt. try laying on my right side and I get this burning sensation in my ribs after a while since that's where Mr. Chunkybutt is. switch to laying on my left side and then my right leg is pressing against my left calf that keeps having muscle spasms. -.- please son!! this hurts!! 😡😡👊👊👎👎
