Hi, I vomited on Friday morning then afterwards felt very heavy, achey and weak and slightly nauseous. These symptoms started to settle down last night so today I attempted to shower, dress etc but as soon as I had ans since then, I've had a nausea/dizziness whenever I attempt to sit up, move my head or walk about which I have to do slowly. I have had vertigo in the past but coupled with the previous symptoms I think it may be something else - possibly viral? What's your opinion Doctor?
