Had vertigo on and off for 3 years! Never been to dr as I've heard so many folk with similar but drs not able to do much! I've got a bout just now following swimming and am fed up with it. Is it worth seeing a dr. I've had a really bad day and feeling a bit swim my even just sitting here. Normally it's just when I turn over in bed or put my head back. Am concerned it's something a bit more sinister. Is it ever or just benign???
