Hm. Well, I've not really heard of a tongue issue with panic attacks. I've heard of that with an allergic reaction (like a peanut allergy or food allergy as the first symptom). But, this is something you get and have tracked so in a way, this is a good thing. You can plan for the attack and start doing your coping exercises, deep breathing , etc. Try not to miss your Zoloft to keep consistent coverage for your anxiety disorder. Stopping abruptly even for a day will not feel good to you. :>)
