I am of an age that never suffered from allergies you just put up with stuff*.
I recently developed a very metalic taste in my mouth.Eating bread was most uncomfortable and other favourite fodder
quickly seemed to be a trigger.I mentioned this problem to Daughter 2 in an attempt to get a little sympathy.
Ah! say she and gave me a cooking magazine that pinned the problem to the consumption of pine nuts.I had eaten cous cous with pine nuts two days previously.Not all pine nuts, but some that come from China.It seems some factors are bulking out with a type of pine nut that causes this problem.It now seems to have gone after about 10 days.Much more info on the Googles under Pinemouth/Pine nut syndrome.
*I developed Rhinitis a couple of years ago.Doctor Wu(named for Steely Dan) told me to get rid of the old Jack Russell and the problem would go.I was allergic to the old fellow.
He even went so far as to draw to imaginary 6 guns when he saw us together and fired a few shots at the old mut.
Anyway dog has been gone 6 months or more now and guess what i am still snuffling.
Now riding again..upto about 5 miles a go so far.Legs getting stronger by the day.Will need to buy my posh bike back at this rate.
