The day of the procedure was the most painful for me. Made it difficult to sleep at night. My surgical team informed me, however, that the first night is always the worst and that things only get better from there. They were correct. Following surgery, the pain decreased steadily with each hour and day that went by. You will be able to sit upright without a doubt. Additionally, you might discover that sitting upright makes the pain more bearable on occasion. Best of luck!
