yes mental pain can cause real physical pain! Just a thought, are you tensing up, grinding or clenching your teeth during your flashbacks? you may not even realize what you are doing physically during those times.

tensing up and getting pain in my teeth its actually very painful.
like its going down my face.

The body and mind react to each other. Have you tried physical relaxation exercises? Also some find yoga, message, meditation, even physical workouts a way to move beyond the physical tension.

I do hope yours continues to subside as time goes by.

Yes, I still get pain from stressing my body out with PTSD flashbacks. They hurt very physically, and I've been hospitalized for them. Meditation helped me, too, in the long run. I recommend it, whatever kind you choose.

Just this past year I have been very ptsd affected, feeling memories. and having muscular dystrophy plus fibromyalgia, nerve pain...my pain is all the time. But the jaw and teeth can tense up badly. so I taught myself how to stop clenching--my teeth and jaw muscles. I stopped. I have done it since teen years. Ended up with Root canals done. Basic wear on my teeth. So stopping that, my body still gets tense. Trying to use relaxation techniques help others. My body pain from MD and the disorders is constant. WALKING and exercise helps me a lot. but in the winter time I can't walk. So I do BREATHING exercises. It relaxes your body. I hope you feel better and get through this.
