Your : Your symptoms could be indicative of many issues.The shortness of breath with simple moving and exertion is a worrisome sign of a cardiac issue or respiratory issue ( i.e. Heart disease and asthma). The burning in your quads can be a sign of dehyration or Lactic Acid build up; and the increased thirst can be a sign of diabetes. The bottom line here is to have a complete physical, and appropriate diagnostic testing as deemed necessary by your doctor. I hope you find answers soon. Best of luck.
