Hi Matthew, Welcome to PC. Have you seen primary care physician? If not, I suggest that's the next thing for you to do. Let the physician know exactly what's going on with you and the fact that you had a psych evaluation and you've been diagnosed with PSTD but aren't sure about the diagnosis. The doctor will probably do a complete physical exam and order some blood work done on you. There are some physical conditions that can cause your problems or contribute to them. If you've already done that and the doctor found nothing then maybe you should go for a second opinion.

Good luck and I hope you get to the bottom of this.

Be well and take care,
