if you are asthmaic it isallergy
it means you are known to have allergies
thing of any medicine taken
our body tries to fight with the allergens may be food pollens and others till our immunity is good to tolerate and age goes our immunity level goes and at time it comes below desired level our body reacts to same things which it was tolerating bedfore
i give my patients a list to avoid
almonds,coconut,walnut,ground nut,peanuts.mustard
they definately cause problem at one time or other in the life
i think the reson is this
but you still think if you had any
medine just brefore eating peanuts
or xposure to any other allergen
you can get blood serum tested for specific
antibodies for these things and go for
sublingual immunotherapy to increase your immunity to prevent such attacks in future
