Thank you for getting back to me. I'm sorry you are having to go through this. Your chameleon has symptoms of Metabolic Bone Disease (MBD). It can take years for MBD to progress to the point where it causes symptoms, and once it does, it's very difficult to treat. MBD can result from too little vitamin D, lack of calcium, too much phosphorus, or an imbalance of these and other nutrients. Laying eggs can deplete a female's body of calcium in a hurry.
There are some things you should do if you hope to save your chameleon. One is dust her food with calcium powder. Second, if your climate is mild enough to take her outdoors, carry her out for a supervised sunbath every day. Make sure that UV light actually provides UVB light. A Reptisun 10.0 is a good brand that does. If you choose another brand be absolutely certain it provides UVB rays. Don't take the word of pet store personnel, but read it for yourself. Full-spectrum, DayGlo, daylight, UV, and UVA are NOT the same thing. I'm putting a lot of emphasis on this because it's crucial to a reptile’s health. UVB bulbs must be replaced every six months as they lose their effectiveness after that, even though they may still look fine. Light that comes through a window isn't sufficient because the glass filters out the Finally, you should make an appointment with a reptile vet. The vet can make a certain diagnosis of the problem, which of course is impossible with only an online description. Then, if MBD is present, the damage will have to be assessed, followed by proper treatment.
Here is a directory where you can find a reptile vet:
If you have more questions, just let me know. I hope your chameleon will be able to recover.
