Hi JJSshim and welcome!
Well it sounds like you have checked out medically, and due to your profession, I am sure that you received great care!... that is always a good place to start, and since it does not seem to be physical, then you can probably put the focus on treating the anxiety.
Did these symptoms come on before you started your meds? I just want to make sure that it is not a possible side-effect, rather than an anxiety symptom, as it can be hard to distinguish between the two sometimes..but it sounds like this has been going on for sometime, so assuming that it's anxiety, then I would recommend breathing exercises.
Not just occasionally, but twice to three times a day, plus more as needed. A lot of 'head' symptoms can be from hyperventilating, that you are not even aware of doing.
We have some breathing exercises is our Reource Guide, and I'll post my favorite here for you as well. It clears my symptoms up in no time:)
The Divided Breath:
Think of your lungs as having 3 equal parts: the top third, middle third, and bottom third. In one continuous breath, but divided into 3 parts, fill first the bottom and pause, then fill the middl/pause, and finally the fill the top third and hold if possible for a second or two. Exhale in the same manner, but reverse. Let out the top, then the middle, then the bottom third of lungs-remember to pause slightly after each part-finally pushing all the air out of the bottom third of your lungs to complete the cycle. Don't worry if you can't manage the whole cycle at first, it will get easier. The pauses will get more controlled, and you may be able to hold the breath for 3-5 seconds before the exhale, eventually.
This will prevent rapid/shallow breathing (hyperventilation) and put you in control of your breathing again, until your anxiety levels drop, and it becomes normal/automatic again:)
This has helped me through a lot of breathing episodes. Remember that breathing is an automatic response...until our anxiety gets in the way! Practicing these techniques will really help get it back to normal.
I hope that you will contiue to post with us...this is a great place for support and sharing!
Take care,
