This is really interesting- I've been suffering with prolonged antidepressant withdrawal for a year now and experienced various symptoms including aches and pains. Over Dec and Jan I had really bad rib pain in my back, upper right hand side. It also felt like in between my ribs were sore to touch and I could feel them clicking and rubbing as if they were enflamed. I went for a chest X ray but all was clear. It's interesting and relieving to hear that others are experiencing these symptoms of anxiety too- they are fibro type symptoms x
