I Am A 68 Year Old Male. Pretty Good Health

I am a 68 year old male. Pretty good health still. Have had headaches daily for 3 to 4 of weeks now. Have had 2 "spills" of queasy, my eyes feel like they were crossing, legs felt like they were prickly, felt nausea. Only lasted 30 seconds and then went away, but still had headache. Thank you!
