Help Shedding
You could try alsorts of things but I went to vet a month ago with same problem, there was a stubborn bit of skin left from shed. It was like a small elastic band about 1 inch from the end of his tail. The vet had a look, and I told him all the tricks I tried, baths sack with wet towel, all kinds of things but they all failed. He said the best thing to do is use a product called Aqua Gel (in UK) its just a water based solution that keeps the tail very moist, when handling, give the snake a good dose say last few inches of tail. Have some of the gel on your fingers and has he glides through he covers himself !!Do this twice a day, after a few days the skin will break free, I found it works perfectly well, and causes less stress to the snake unlike trying to give him a bath or some of the other methods. Although some snakes do like a bath, mine doesnt. Also some vets would give you a similar product but charge a fortune for it. I would definately not use tweezers... are you sure that it is still skin left from a shed or is it an injury that is trying to heel ?? either way the Aqua Gel wont do any harm, if it is an injury then the gel seels the area from infection to a certain degree. Best of Luck.. ;-)
