I'm considering looking into having rumination syndrome because I have abdominal pain and regurgitate my food involuntarily; I have been diagnosed with GERD but I just want to cover all bases because the treatment I've been getting for GERD hasn't gotten rid of the regurgitation. I was wondering if along with unintentional regurgitation, if people with rumination syndrome can intentionally regurgitate their food if it hasn't been too long since swallowing, since that is something I can do that nobody else I know can do.
