I was diagnosed with a Penicillin allergy in 1991.  Subsequently,I developed sensitivity to peanuts.  I am 66 yearsold,female.  I tend to have problems with nonspecific itchiness....the middle of my back, then the palms of myhands will itch.  No rhyme nor reason it seems.  I was also diagnosed with allergy induced asthma when I developed the penicillin allergy.  I have done well the last few years and have not needed any inhalers.  I seem to have weird symptoms now that Im older, such as the itchiness,but also experience my tongue becoming irritated for no apparent reason, or a sore throat will develop.  I must say none of my symptoms are particularly serious, just annoying.  Any thoughts?
Allergies when not treated tends to recur and can start giving symptoms at any time when you have allergy to one substance it may increase to multiple things as immunity decreases you can take continuously antiallergic like basting 10 mg once a mayor get tests to get full cure by immunotherapy
