I agree that the symptoms are both mental and physical. For me because I also have other issues that cause me pain, I am getting to the point of knowing WHICH problem is causing what. What I have noticed when I was on the pain killers, they might have taken the back pain away BUT did nothing for the pain from the PTSD. For my being physical is both a mental and physical challange and cause such great fatigue. I have to always be aware of what I am doing and watch my balance so closely. My house looks like a POST IT WAREHOUSE, so YOU BET CHA it is both.
