hi lil bit......I have the same thing happen at times and it is a anxiety attack.......a panic attack to me is much more severe. They can lead to the full blown attack if you let it. When I say let it I mean don't allow the feeling to scare you...go with it and tell yourself "ok I know that this is my anxiety I'm getting a little excited and it will pass and I will not go crazy. Breath thru your nose and talk yourself into relaxing and that it's going to be ok. Just keep doing what your doing and you will be just fine...take care and god bless.
