Urinary tract), medication side effects, pregnancy, ; even reaction to stress. Find ; treat the cause--see doc.

GI reflux(GER): Ger can be acute, intermittent or chronic. Sometimes life style issues can contribute such as being overweight, smoking, alcohol and eating habits. A trial of over the counter proton pump inhibitors can help but if the symptoms persist or reoccur it is better to see a gastroenterologist.
