For years I have been dealing with this "anxiety" business. My legs get heavy my feet throb. At times I feel I have to keep moving my legs and others can't stand the thought of moving my body at all. I get light headed and more often than not I'm am so unbelievably tired it brings me to tears. The only way to describe my episodes is like labor contractions. They come on slowly, get worse, peak then begin easing up for a few moments then start again. My knees ache and feel weak I thought it was arthritis because I can here a clicking sound when I walk upstairs and I have to pop them almost every day or they feel stiff. I get bad headaches brom the back of my neck to the back of my head and my ears. It almost feels as if something toxic is running through the mid of my neck to the back of my head. I don't know if all this stuff is related, I just know it is super exhausting. I try to relax and use breathing techniques but it still miserable. Suggestions??
