I found out today I was allergic to black walnut tree. What are the some of the the syptoms in case I run into one?

Classic symptoms. Try not to run into one as you might get bruises and cuts and scrapes...Haha. Seriously typical allergy symptoms are common. Runny nose, congestion, itchy watery eyes, sneezing or even asthma symptoms of wheezing and cough. The problem is that tree pollen can spread for miles around, so you may not even be aware of the walnut tree and still have an allergic reaction.
