Hi, and welcome. I have anxiety and fibro and experience most of the symptoms you describe, especially the leg-thing. I don't feel a heaviness but the 'tightness'...almost like the skin has contracted around the muscle and bone. My feet feel like they are swollen(they aren't) and I get a sensation like there is cold water dripping on my skin. Pain also in all the places you mention...a gnawing ache.
I have had all kinds of tests run and have been told it is anxiety and fibro.
To ease your mind, my advice is to get checked out by a doc who takes you seriously. Take it from me, worrying about what it 'could be' will only intensify the symptoms. And this is just my personal opinion...Googling symptoms is the worse thing you can do if you have anxiety.
turmoyle, it is nice to meet you. I had alot of your anxiety symptoms too. Before I was dx'd with Fibro I lived in a constant state of fight/flight. Every muscle in my body was tense & I couldn't seem to relax no matter how hard I tried. I had those tension headaches that crawl up the back of your neck , up the back of the head & over into my eyes. I did seek out a theropist & found I was so depressed & stressed out. An anti-depressant was helpful. I also found I was allergic to soy, which is in everything processed now-a-days & that was a large contributing factor to the fight/flight feelings I had. Too much adrenelin pumping through my system, my bodies way of fighting the soy. Lastly, was the dx of Fibro & the decision that I had to lead a simplier life, a more peaceful life. You are definitely on the right road. So, get yourself a new Doctor who will listen to you.
I had a problem with getting across to doctors that I was in pain. I guess I didn't make it "loud" enough because I actually had a doctor say, "Well, you don't seem to have much pain to deal with", & that was after I had told him where I hurt. I have a tendency to hold it all inside but maybe if you are not being heard you need to be more vocal about it. I have learned this myself.
