HI Brian
I would listen to Anita because I know my doctor says there is a high link between depression & anxiety & there are some really good medications out there to make you feel better.
I have headaches (that stem from tense muscles in my neck - so much so that on one side you can actually feel a hard lump {which of course scares me, but it's muscle contracting} which my doctor put me on a very low dose of amitriptyline only about 2x's a week. It helps my headaches, but I am actually not depressed (but like I say, most people are and don't realize it with the anxiety) so I personally find the next day after I take it in the PM, I am very tired.
I just wanted to say that I get the cramping too. My doctor said to try to get more calcium because anxious people tend to not eat well or, like me, don't really feel like eating. Mine were off & on for about 3 weeks, with pins & needles, but the last couples days has been better.
They say there are many faces to anxiety - that's what makes it so frustrating. You finally get a set of symptoms "under control" (even just mentally), then you get a whole new set later on. It's just the nature of the beast. I think this is why so many have been at our doctor's offices so much (& it's good to get things checked out!).
Wish you well
