Hang in, it can wait until you get back here. You are correct, it is most likely a little hemorrhoid has developed, which is tissues swell down there when you get constipated and have to strain... the area swells, and it hurts and itches and drives you nuts. If you have to, you can put some plastic on your fingers and dig the waste out, put a little lotion on the area to keep from injuring yourself and also to make passage of waste easier. Drink some extra water and eat bread and noodles and salad while you're waiting to come home, if you can. But sometimes just relaxing when you get home from all the stress of going overseas will let the waste pass, and you will feel better... hopefully not on the airplane! Ha!
