<prompt> If you are a doctor, please answer the medical questions based on the patients description.chronic dizziness 6 years no obvious cause. worse pre menstrual. worse if I ve had alcohol for a few days after. had mri, ct scan, heart monitor, seen a physician and a neurologist. There doesn t seem to be any answers. it all started many years ago after having anaemia and then coeliac diagnosed. Before that I was fine.  <response>: HI. Thanks for an elucidated history. You are suffering from dizziness for 6 years. Gets worsened just before menstruation and after alcohol. Both these conditions indicate that there is swelling of the semicircular canals during these conditions which increase your problems. I would advise visiting an ENT Surgeon who can perform Calorie test and positional testing to elicit the vertigo nystagmus. The treatment can be in the form of diuretics, bed rest, may be surgery to leak out the opposite of the semicircular canals.
