DD has appointment in a few weeks. She has undiagnosed stomach problems (alternating diarrhoea and constipation, quite severe) and over the past six months her eczema (which she's had since 6 months old, but mildly) has flared up and has been really bad. Am desperate to find out if there's any link between these two problems and whether she has any kind of food allergy/intolerance. Has anyone used this clinic and, if so, what was your experience?
