Vertigo and Pregnancy

Hello ladies anyone who can offer an insight would be greatly appreciated.

I was diagnosed with vertigo by my GP after a viral infection of the throat in November last year (2009). It gradually got better and improved and by the time I saw an ENT in January 2010 the symptoms had all but disappeared and the specialist said i was on the mend.

Anyhoo i then got pregnant and at 9 weeks i had a severe vertigo attack in the middle of the night with nystagmus (quickening of the eyes) and have had another 2 since then (I am now 17 weeks pregnant). I feel off balance all the time and the dizziness seems to constantly be there and makes me SO tired. All i want to do is sleep 24/7 which you cant when you have a toddler as im sure your all aware!!

I just want to hear from anyone out there who has had vertigo during pregnancy and can tell me if it disappeared once you gave birth or offer any treatment to help a little.

I go to the physio once a week which helps 50% of the time. Im at my wits end and feel like i cant deal with the impairment anymore.

Thanks again.
