My 34 year old daughter, has been vomiting every single morning for the last 20 years! It starts as soon as she wakes up and last a couple of hours. The only medical condition she has is Hidradenitis Suppurativa, onset at the extremely early age of three. Her HS is rated as severe. All her doctors over the years and this includes many overseas specialists, say there is no correlation. She has tried everything to have it go away, but nothing works. I am so worried about her and sad for her. Does anyone have an experience that is similar? All the medical literature just talks about vomiting that lasts for a few hours or days, none for 20 years! Thanks so much, Becca's Mom
