Am I allergic to potatoes?

About 5 months ago I seriously cut down on carbs and starches to loose some weight and get back to a healthy lifestyle. I used to eat lots of white rice, potatoes etc.... The past two weeks however I got married and went on my honeymoon where I splurged and let myself eat what I wanted to, although with moderation. During one particular meal I ate 1 1/2 potato skins. Not to be too gross, but I was bloated, aching and gassy for two days, it was crazy! During the trip I also ate more sugar than I was used to, I ate bread and white rice....but nothing else made me feel bad, it was solely the potatoes. I know this because it happened at Easter as well when I ate a few scalloped potatoes, the pain was just not as bad. Anyway, I am trying to figure out if I have developed an allergy to them or if by cutting them out for so long my body doesn't like processing them anymore. Hopefully there is someone who can shed light on this situation! Thanks so much!
