What Does The Swelling In The Entire Body Indicate?

Hello, My entire body swells up in the morning, almost doubles its size, then after about 2-3 hours it goes back to normal. Sometimes I experience chest pain, (infreqently spine pain, overall body pain), having trouble walking in the morning, and rarely I vomit. I am female, 40 years old, I am of average height and weight, I don t take any medications whatsoever, I keep a healthy intake of food, I rarely consume alcohol, no family medical history. I already scheduled an appointment with my doctor for next week, but I d like to have an insight as to what this might be. Thank you.
