http://www.ncbi.nlm.nih.gov/pubmed/15992471 "The prevalence of migraine and allergy was significantly higher in patients with MD compared with age- and sex-matched controls (p > or = 0.005). In addition, the prevalence of allergy was significantly higher in patients who had both MD and migraine (30/42) than MD alone (26/66,p = 0.002). However, there was no link with any specific allergy types. This study suggests that migraine and MD may be linked by an immunological determinant." Interesting speculation regarding the possible link between Meniere's and migraine...
Interesting find.I and many others wonder what the commonality is between the 2 conditions. Immunological looks like the way we are heading here.
