How long did the tingling last - If this was only upon awakening and disappeared within a short time, it is possible that you were sleeping with your wrist bent - this is a classic sign of carpal tunnel syndrome. The tingling ffom carpal tunnel would be mostly the palm of the hand along with the thumb, index finger, middle finger, and adjacent side of the ring finger.
If there are other signs of tingling in the legs or face, you should see the doc.
The shortness of breath may be a sign of deconditioning - when you walk up and down the steps you use more energy and the muscles demand more oxygen. If you are out of shape, there will be an even bigger demand for oxygen. This may be more than your body can comfortably deliver, thus the faster breathing and feeling of breathlessness.
Since you are overweight [though you do not give your height] you may want to consider evaluation for an exercise program that would safely recondition the muscles and allow you to move about more freely.
