from what it sounds like to me he definitely has some ri a herpvet visit would tell you for sure. vets can be expensive but meds not so much.your going to have to inject your snake with something as the doc prescribes and get everything stable and do what was mentioned in previous posts with the temps.the injection sometimes can be very difficult depending on the size and temperament of your snake.injecting wrong could possibly do damage,death or not work.possibly every snake owner has had to do it at one point,i think?
