is there a virus causing dizziness and sickness

Are you drinking enough pably? In this very hot weather I drink a glass if water in bed before sleeping. OK I know it makes me visit the loo more often - but worth the trouble! I also drink a glass of water in bed before getting up. This has made a huge difference to how I feel on waking. No more feeling anxious and ill first thing! When I wake in the night I ofen take a quick swig from the glass. Sometimes we simply don't realise we are dehydrated!!
Hope you improve soon , failing that a GP appointment may be of benefit. Good luck. Water 💧 water 💧 water 💧!!!

Pably15 it could possibly be benign paroxysmal positional vertigo (BPPV). My daughter has had a few bouts of it recently and what you describe are the symptoms she had. It's worth getting it checked with the doctor, they prescribed her some anti-sickness tablets and exercises but she paid to go to a physio, which helped her enormously.
