Have you been on any ABs recently? I began to get reactions to eggs and soya after having to take 'vicious' ABs for cellulitis several years ago, but after excluding them from my diet for a year, I was able to reintroduce them back. I had the support of a nutritionist.
My DD, as I've said before, is allergic/intolerant to both eggs and dairy in any form. She is healthy. GPs have shown no concern or even interest when she told them.
PS My son, a paramedic, was as bad when I had pneumonia. He sent me an oximeter and I had to use it every day, while on FaceTime, to reassure him I was ok! Sometimes people know too much! It also shows how much they care.
