Eh, don't worry about the spelling. I see some of the most experienced keepers mispell that word more often than not. Glad the seller was willing to take her back from you. That kind of post sale stuff seems to be the rarity these days. She could indeed have a serious problem and it would really suck for you to have her just die and leave you up a creek. From your recent description, they could have just gotten infected somehow and caused blindness (permanent or temporary) and is just not beginning to go back down to normal size. Whatever it is, I hope the girl makes it through alright.
