Certain problems are more likely to occur with PTSD. They include panic disorder, agoraphobia, obsessive-compulsive disorder, social anxiety disorder, phobias, depression, sleep disorders and substance abuse. These disorders sometimes precede PTSD, but may also develop after the onset of PTSD. For more information on social anxiety disorder, visit socialanxiety.factsforhealth.org.

Other medical problems like skin problems, pain, and gastrointestinal distress, also seem to be more likely to occur in those suffering from PTSD. Fortunately, successful treatment of PTSD often results in the cessation of these problems.
