Welcome to our forum, gonelikeyesterday!
I'm sorry that you are feeling so many somatic symptoms all of the sudden. To answer your question, it is not at all uncommon for the things you describe to pop up months or years after your thinking brain has processed trauma. In my own case, it took many years to first realize that I had cptsd and then a few more to really work with my body on things such as anxiety, eating disorders, and now tinnitus.
Hang in there, and look around the "resources" section for suggestions. Many of us have gotten a great deal of help from author/therapist Pete Walker's books, and Bessel Vanderkolk has written a book entitled, "The Body Keeps the Score" which is full of interesting ideas. Peter Levine is another therapist/author with much of interest to contribute here. And there are others.
You are not alone, and your symptoms are not at all unusual for trauma survivors. I am glad you found our forum and had the courage to join. Take care and be gentle with yourself.
