Around 10 am this morning i started feeling sick and light headed out of nowhere. now i'm exhausted and have a headache on top of that. what wrong?

See below: When a patient experiences feeling sick and lightheaded, followed by headache and exhaustion it would be important to know if by sickness he or she meant nausea. If the feeling was nausea then it's possible the person was having a migraine headache. Health Tap Questions is not designed to diagnose illness, but rather to answer general health questions.
