I wonder if they are more prevalent in Caucasian's rather than other Ethnic groups. I'm white and have allergies to antibiotics and adhesives. I started having problems when I had Appendicitis back in 1979. My first daughter had to be delivered by C-section in 1988 and that's when the night mare really began. I was able to have my second daughter naturally in 1991 and in 1992 I ended up having several surgeries including a hysterectomy. I had my last surgery in June of 2006 and haven't been able to work since then. I'm still fighting to get social security. I go to sleep every night hoping I never wake up again. Thanks for letting me vent. Wendy
