I’m so sorry you are experiencing these symptoms. I think you’re absolutely correct in pursuing a physical cause. Lots of doctors dismiss physical symptoms as psychological problems and fail to see the mind/body connection. It wouldn’t hurt to see a psychiatrist though. My experience has been that psychiatrists often DO see the mind/body connection and can help diagnose physical conditions that other doctors miss. Hang in there and know that I am thinking of you and offering support no matter what the circumstances.
