So for the past couple years I have been extremely stressed, marriage troubles. But anyway back about 6 months ago I started having heart palpitations, and panic attacks, (I was diagnosed with Panic Disorder and GAD years ago),this is something I have dealt with off and on since being a kid.But anyway, I am now sore all over from Muscle tension, my feet, my arms and my legs due to fatigue and exhaustion. My sternomastoid muscle in my neck is swollen, the Dr says from anxiety, so he put me on Celexa a couple weeks ago and I just started taking them 3 days ago and having more anxiety it seems since. I was so scared to take the pills, they just set there for a week before I decided to take them. Can someone plz tell me if the anxiety gets worse before better when taking antidepressents?
