Thank you for waiting. This tortoise has classic symptoms of Metabolic Bone Disease (MBD), so the vet was on track with a calcium supplement. However, that doesn't go far enough. I recommend that you get a new UVB light as soon as possible. We don't know how old the present one is. The lights give off visible light for years, but after about 6 months, no UVB light is emitted. Since UVB is invisible to us, we aren't aware of this. Also, if a coil/spiral bulb is used, they are inconsistent in output. They may put out enough UVB to damage the eyes, or so little that MBD isn't prevented. I recommend the Reptisun 10.0 in the straight tube style.
Also, pick up a cuttlebone. These are sold in the bird department of pets stores and are very inexpensive. Just place it in the enclosure. Don't use the holder that comes with it. Most tortoises will eat cuttlebone, and that is a good source of calcium. Kale, and a number of other so-called calcium rich foods actually promote MBD. The calcium they contain is in the form of an oxalate, which binds calcium to a form the body can't use. That leads to a deficiency. I suspect you got your information on feeding from a pet store, an outdated book, a misinformed breeder, or a less than reputable website. Unfortunately, such information is often incorrect. Those commercial foods are worthless. Tortoises need a high fiber diet. Greens are important, but greens alone don't contain enough fiber. Hay and grasses should be a big part of the diet. Buy some tasty varieties of hay. Oxbow packages high quality hays for pets. I found one company that will ship Oxbow products. The botanical blend would be best for tortoises because it has a mixture of hays and herbs:
Of course, greens such as dandelion, collards, and turnip greens are also good, but your tortoise really needs the fiber found in hays and grasses.
You can read much more about diet at the following reputable site:
The same site has a good care sheet:
The only way to reverse MBD is to provide both calcium and UVB. If your tortoise won't eat the cuttlebone, you'll need to find a vet who can provide an injected form of calcium. The vets you saw are actually reptile vets, and they should be able to help with this.
