When i bend over i feel everything rushes to my head n when i walk lile 10-20 feet i get shortness of breath for a short time?

Bending/walking: It is not unusual to experience blood rushing to your head when bending over. Walking 10-20 feet and getting short of breath is not normal if you are otherwise in good health. See your doctor for assessment. All the best.

Shortness of breath: Would follow up today with doctor/ urgent care, ER. Could be asthma,cardiac or rarely increased pulmonary pressure, need to check CBC,echocardiogram d-dimer, and CXR also make sure not anemic, f/u today
