I would like to start by saying that I am going to make an vet appointment asap for this girl, but in the meantime, just wondering if anyone else has seen/heard anything like this.

I got this yearling spider female about 700g. Got her in a trade a little over 2 months ago. She seemed healthy and all at the time. Kept her for about 6 weeks, to ensure all was good, then I started putting her on my table at the shows. About 2 weeks or so ago, we noticed that she looked like she had a kink in her about midway down the body. I took her off the table and back in my racks. Now I just checked on her today and noticed this "kink" has gotten larger. It is a large ring all the way around her body. The only way I can think to describe it is like a rib that is 50% larger than all her other ribs.

Has anyone experienced anything like this? She seems otherwise okay. She is acting like herself, she is eating, it does not seem to hurt her when I touch it or anything.
