I used to have panic disorder and it lasted about two months, during that time I would get really really sore pains everywhere in my body. I should shake uncontrollably and I'd twitch alot. I got pains in odd places like my brain, chest, beneath rib cage, arms, fingers, eyes and basically anywhere that involves muscles. I no longer have panic disorder but I still get those pains and it didn't start until I started getting bad anxiety. Can these pains be from anxiety? Can anxiety effect your nervous system?
