I wouldn't worry too much about the vet helping with the stress...but if you have a health concern, definitely. I couldn't pinpoint what was going on, and it turned out mine did have parasites. So I'm glad I went - I think it helped MY stress more than the cham's stress! At any rate, have a vet's name on hand in case you do go sometime. That way you won't stress if you're in a hurry, etc.
