I am 21years old and weigh 150 lbs. I took 150 mg of deca Monday. I now have a nagging pain an my right side. Not sharp but nagging. At first my lower back on my right side had the same pain but it has gone away. I'm drinking over a gallon of water a day and taking cranberry extract. I know you guys will probably say "see a doctor" but I'm wondering if things will probably get better in a few days. How long does it take for the deca to start wearing off? This was my first shot.
