I had vertigo for the first time a month ago. Threw up quite a bit. In the past when I throw up it irritates my throat and causes coughing. Been coughing now for a month and bad headache and occasionally flu like symptoms on and off. Been to the doctor twice. Breathing was labored but chest was clear. No fever. On an inhaler and finally a zpack. Can t say I feel any better? Should I get a chest x-ray?
