Symptoms usually appear within a few weeks after someone has had chlamydia or a diarrheal infection. Most people feel a little tired and have a slight fever, although a few have high fever, significant fatigue and weight loss. Other early symptoms include muscle aches, joint stiffness, and low back pain radiating into the buttocks or thighs.
