I get quite a bit of muscle tension, likely from being tense a lot due to PTSD also they cramp up very easily and such and it seems like I get sore to easily. I think before I had PTSD I had some issues with that kind of thing but not as much I've always had anxiety issues, depression and a bit of trouble dealing with stress so I know even before I developed PTSD I had quite a bit of tension.

I am prescribed 5-10 mg of valium once a day for anxiety, I tend not to take it every day and there are times it doesn't really do a whole lot to help even if I do......I find cannabis can be helpful for anxiety and tension of course its illegal most places. Then there is valarian root and other herbal remedies that can help calm anxiety that I've used as well.
