This happened when I was about 14. I didn't know yet I was allergic to horses. Maybe I was tested for it, but back then I was really in denial about my allergies so I didn't pay attention to alot of stuff.
Some friends wanted to go horseback riding, and I had never done it before so I thought it would be cool to try. Being spring, pollen was bothering me some, but I was just mainly sniffling and had some sneezing. I hated using tissues back then and I usually could just sniffle and be ok, so I just kept a few tissues in my pocket.
We got there and everything was ok for a while. A few minutes after we got on the horses, I noticed that my nose was getting very stuffy and it was tingling pretty badly. My nose started to run more and I was trying not to sneeze. Eventually I couldn't keep from sneezing because of this constant tingle all inside my nose. I kept having sneezing fits while we were going around on the trail. People kept asking me if I was ok, and I would just nod yes because I didn't want them to hear me sounding all stuffy. My nose was too runny and I went through the few tissues I had pretty quickly. I kept on wiping my nose on the inside of my shirt and I was trying really hard not to let anyone see my nose being snotty. My friends kept looking at me when I kept sneezing and I could tell that they felt kinda bad for me and I just felt more and more embarrassed because I couldn't go run off anywhere.
By the end of the trip I was feeling miserable and I probably looked it too. As soon as we got off the horses, I told my friends that I would be in the car. My nose and sinuses were all stuffed up and my eyes were all itchy and puffy and watery. I got in the car and I just kept sneezing and sneezing. I couldn't find any tissues so I kept sneezing inside my shirt and kept trying to wipe my nose as much as I could.
I was bad like that the whole trip home. My friends kept asking how I was and they were acting all concerned and I was really wishing I could be away from everyone. I wanted to die from embarrassment. They were going to hang out but I asked them to drop me off at home 1st. They did and I just went into my room and felt pretty miserable for the rest of the day.
Since then, I haven't ridden on a horse and I haven't been around any that much. Out of curiosity I have been around one for a bit every year or so just to see if I am still allergic (I do that with most things I am allergic to that I usually can avoid), and I am.
