It is not so uncommon for people to develop allergies to various things like what you have experienced, later in life.
One can, in fact, become allergic to things that they have been using for a long period of time.
The exact cause of why this happens is not known.
The best thing to do, obviously is to avoid things that you recognise that you are allergic to.
If symptoms are severe then you will require medications to help suppress your allergies like antihistamines, topical steroids and so forth.
This session is open for any further questions that you may have. I would appreciate it if you rate me by clicking on one of the rating options at your end on the top right hand corner as that is the only way we, the experts, are credited on here for helping you out.Kindest regards
