Hi and thanks for the query, period abnormalities mightbe oberved at some point in a female s reproductive cycle. But it becomes repetitive or nintense, it deserves an appropriate clinical evaluation. Causes could be benign, hormona, infectious, ovarian or uterine depending on the case. You might have to consult your gynecologist. Heat burn, usually known as gastroesophagal reflux disease could actually present itself with repsiratory distress. Its however very important for an appropriate diagnosis and extent of the disease to be made. A clinical evalaution coupled by a pH measurement in the lower esophagus and a fibroscopy should be sufficient. Other tests like a chest X ray could be done to exclude other lung or heart causes fo respiratory distress. I suggest you visit your primary care physician for a proper clinical evaluation and orientation to aspecialist if necessary. thanks and best regards, Luchuo, MD/
