Leg aches and dizziness for a week- I want my life back!

Hey, guys. So I’ve had anxiety disorder for most of my life, but this is a new symptom and it’s really freighting. I had excruciating anxiety all week. Horrible, almost unending panic attacks. The anxiety has since calmed, but now I’m left with this scary new symptom- leg pain, accompanied by dizziness. I’ve always had dizziness but with the leg pain it seems worse, and walking (even around my home) seems impossible. Mind you, I’m 23, active and healthy. My legs crack like crazy when I get up, and it feels like I did a strenuous workout. I usually write this off (being used to it and all) but it’s been a week and I’m lying in bed because of the alarming feeling of walking. I ran 2.5 miles yesterday to “prove” it was all in my head. Of course I did fine, but the anxiety returned almost immediately. I’m just looking to hear if you’ve had similar experiences. 

Ommgggggg I'm going through the same thing and loosing my mind I keep thinking blood clot blood clot but I don't have blood clot symptoms forreal the back of my thighs are extremely sore like I've worked out or something I'm 22 and I have been laying in bed lately my anxiety is definitely starting to come back too.. so idk maybe it is just anxiety I read that it can cause all types of muscle pains and aches 

I'm having the same problems myself it's happened before it goes away but when it comes back it's just constant blood clots and terror but sure as soon as I move about its gone when I rest it's back again driving me mad
