This sounds like hyperventilation which causes a rapid low level of carbon dioxide in the body. Low carbon dioxide levels eventually lead to narrowing of the blood vessels that supply blood to the brain. This reduction in blood supply to the brain leads to symptoms like being lightheaded and tingling in the fingers. Severe hyperventilation can lead to loss of consciousness.
This would be the case in both getting angry and the laughing episode you describe.
The symptoms you describe would not indicate a tia although the hyperventilation can be related to panic attacks.
I also feel symptoms after hard workouts. Could this be hyperventilation as well? Is vasovagal a possibility?
This would be in line with hyperventilation as well and would apply in all the scenarios you describe. If it were vasovagal normally you would feel VERY hot (flush) and rinninging in the ears alone with the other symptoms of hyperventilation.
So that is not likely the cause of your symptoms.
Ok. Thank you very much for your time.
