Hello, I Have Been Suffering From Chronic Swelling All My

Hello,
I have been suffering from chronic swelling all my life. Now I have frequent urination AND chronic swelling in my face, ankles, legs, my whole body. My Dr. keeps doing tests and can't find anything wrong with me. I started taking antibiotics for my acne and it improved the frequent urination but I still get up 5-8 times at night to urinate. I am 61 years old. I gained about 20 lbs almost overnight and the swelling has increased in the middle of my body for the first time. Denise
