my daughter has 12 to 18 short but very major attacks per day. her symptoms are shortness of breath, chesty cough, numbness in extremities, clammy hands. these attacks can occur at any time with no specific trigger. She can be asleep, watching TV, in the street or even in the Doctors surgery. She is on antidepressant s and is due to see a physiologist within 2 weeks. meanwhile the attacks continue unabated.
