you can NOT base previous reactions that have been mild and judge that that you are mildly allergic.
as for eating food that are labeled 'may contain' it means just that,'may contain' there may not have been any peanut in that food. also if you are only allergic to peanut, the majority of nut contamination is tree nut.
most immunologists consider that a peanut allergy past the age of 7, is a life long allergy, the 20% outgrowing window is most often before that age.
not every allergic reaction moves on to full blown anaphylaxis, it depends on many other factors such as,
amount ingested.
health at time of ingestion, such as recovering after a viral infection, or illness such as chest infection.
poor asthma control, speeds up reaction.
alcohol,
exercise,
other allergies filling allergy cup, such as environmental allergies at the time, like hay fever , tree pollen.
peads are often our only source of medical advice, and this is because there is not enough nhs full time allergy clinics around , and our peads, asthma and skin consultants have had to fill in the gap in the massive rise of allergic people in the population. this means that poor support leads to people coming to the conclusion that they are mildly allergic, and take unsuitable risks, like eating in ethinic resturants such a indian take aways.
I think that this poor nhs support leads to parental mistakes like this, and is not always the parents or the allergic persons fault, they have never been properly supported medically with their condition.
sorry for my small rant, but its a subject dear to my heart.
