Sore wings and vodka

I have always had a problem with vodka. When I drink it, I get sore wings - they kind of ache and make me feel uncomfortable. My housemate, The Pond, disputes this. I fear she might be right, which I find hard to admit. I have always liked blue cocktails, especially when they have little umbrellas. Generally, blue cocktails contain vodka. I have, mostly always, got sore wings after drinking blue cocktails. Other cocktails have left my wings feeling light and free and, well, non-achey. Other cocktails often contain vodka too. So, The Pond, in all her wisdom has deduced from this that it is NOT vodka, but instead the blue stuff. I think she may be right. So, I fear I may have missed out on, oh, ten years of vodka-drinking, purely due to misinformation given to me, by... me! Does anyone else suffer from sore wings when drinking blue cocktails, or am I some kind of human anomoly?
