Hello and welcome to the A/P!
It sounds like an anxiety response, but also make sure that you are eating regularly, as this can also be part of a hypoglycemic (low blood sugar) episode...especially if it happens after physical activity.
Most likely though, through some coping mechanims such as breathing and relaxation exercises, it should be relieved. (we have video links to such skills in our Resource Guide here, main page 1st post)
Post anytime, and be well.;)
