Jamie,
"You don't know what you don't know." That's the problem. I'd trust the opinion of a trained vet much more than the opinion of a self-proclaimed "experienced keeper". It's also better to learn the right way of doing something, rather than learning what someone may have been doing wrong, even if has worked for a number of years.
Cheers, S
When you've been a member on this forum long enough you'll grow to learn that there are some keepers here (and Jamie is one of them) who, due to years of experience, have extensive enough knowledge to comment on posts regarding the condition of an assumed sick snake and either advise the inquirer not to worry or inform if they believe the snake is suffering an illness.
You'll also discover that those, such as Jamie, who are very experienced within the herp husbandry and bother to take the time to contribute and offer an opinion are doing so out of concern for the welfare of the animal and will advise to consult with a vet if they consider the condition is serious enough to seek veterinary treatment.
It has been proven time and time again where people who have not trusted the initial diagnosis provided by the "experienced keeper" have gone ahead and consulted with a vet to satisfy their curiosity only to repost to confirm what they have been informed in the first instance, thank the person for their contribution and the advice given as treatment.
I'd consider that pretty experienced considering they are only going off the symptoms described by the OP without sighting the snake.
Unfortunately the vast majority of those trained vets that you refer to (and even in some cases those that are considered experienced and even further those considered reptile vets) don't examine enough reptiles to have a real clue about reptile diseases and are reluctant to declare the fact. Sure they may be able to diagnose some of the more common problems but then again so can those experienced keepers that contribute to this forum and the difference is that it won't cost a fortune to get a diagnosis and recommended treatment.
I don't know how many times I have read posts here and on other forums where people have taken their snakes to a vet only to have the condition misdiagnosed in the first instance.
From what I read here Jamie is just advising that there is no need for those new to the hobby to run to a vet unless they believe the critter is showing obvious signs that they are suffering from a significant illness/sickness or infection.
I hope you might take the time to reconsider your opinion regarding suggestions put by experienced keepers such as Jamie who contribute to similar posts in the future.
Cheers,
George.
