i have suddently developed a mild allergic reaction to peanuts, i am 31 yr old female and have always eaten nuts/peanuts/peanut butter so this is strange. Just a small amount recently caused my whole upper body to itch, and a few red hives developed within 30 min of eating a chocolate with peanuts and the nite before a handful of nuts and raisins. Both times the same reaction, my arms itched especially but it did not affect my breathing. Is this possible to develop a nut allergy so late in life. i did have asthma as a child, outgrew that, have eczema now and then behind my knees, nothing too bad though and i sometimes have post nasal and sinus problems but this gets better with age, i've only ever tested for wheat and gluten and the wheat was positive but i eat wheat everyday with no reaction so i assume the test picked up a grass allergy rather than a wheat allergy.

The last thing is that this has happened just 2 wks after i've started taking 60 mg prednisone for a neurological problem, could it be that the prednisone because it reduces immunity has now made me vulnerable to nuts?
