I have rhinitis too, had this since I can't remember when. Since having my son I have a nickel allergy. Since menopause I have eczema in my ears would you believe!
Mum had asthma
Sister has hayfever
Son has eczema, asthma, psoriasis and bad food allergies (mainly nuts, cherries and applies) he also carries an epi-pen. Oh and by the way, if anyone has a teen etc. who is supposed to carry one but doesn't due to them being so bulky, I've done a bit of research and they are now almost finished trials on epi pens in the form of a credit card so they can be carried in the pocket or wallet. These should be available next year and cost around £40-£50.
Weird things these allergies, they can come on at any time.
