I am a 22 year old female and lately have been experiencing 'weird episodes'. during these episodes i get blurred vision, everything goes loud, i get shaky, find it hard to control my breathing, break out in a sweat and my heart begins to race. This mainly occurs either after a hot shower or during running/ cardio exercise. Last visit to the doctor my blood pressure was slightly high and my pulse was 120 beats a minute. Blood test came back clear for liver, kidney, blood count and negative for diabetes also an ECG was completed which also came back normal.
