I wouldn't want to be the bearer of bad news but I had what I knew was a bot fly, I got it somewhere on AC, have been going for 10 years and I won't let it stop me from going many more times but it wasn't fun. Very painful and the Doc's here in California don't know what they are. I had all the symptoms described on the bot fly posts I researched on this board. It was no worse than all the coral I had to have dug out of my feet one time at the Red Sea or the sunstroke I got from my younger sun worshiping days.
