Hey there-
Well you are on ritalin (a stimulant) and risperdal (an anti-psychotic). Ritalin can definitely make your heart race, make you feel jittery and panicky which can increase panic hence your breathing problem. And being nervous exacerbates the whole breathing thing and other panic symptoms. It does seem like a strange combination of medications. Why would your doctor prescribe both these meds? They would seem to cause polar effects when used.

PS: What you described definitely sounds like my panic attacks!!!! I hate that I am GOING TO DIE feeling!

Well no, I don't do drugs and I don't drink or anything like that. I have ADHD and I'm a bit bipolar. I don't really need the Ritalin actually, but apparently I need the Risperdal. Although my pediatrician is off until Jan 3rd, so I can't talk to him about it until then when he gets back. I only had what seemed like a panic attack once, the first time I felt like I couldn't breath. Now it feels like I can breath, but it feels like I'm not getting enough air all day. Hopefully tomorrow they will take an x-ray and see if anything is wrong inside my chest or anything to that effect. I'll get another ekg done to be safe there. It really does feel like i'm having trouble breathing from the upper part of my chest. I know it's not nothing, so if they say it's not I'll have to wait until the 3rd to get a hold of my pediatrician and talk to him about it. If they don't send me for blood work then he probably will, and might know something the doctors don't. Because when I go for my checkup with him he always asks me if I have any pains or breathing problems, so I think he might know something. Anyway, like I said hopefully tomorrow I can get this all fixed up. All I know is this is a REALLY annoying thing to go through 24/7.
