My chameleon can't move its back legs after getting stuck. Is it hurt?

Give him a day or two to fully recover. Monitor for swelling or bruising. If he doesn't regain full strength, have hm examined by your veterinarian or an experienced herp veterinarian. Increase enclosure temperature to aid in healing and keep him as stress free as possible.

Sounds like MBD. Without more information all I can tell you is that you should take them to see a reptile veterinarian. This could be trauma/injury but honestly, most problems we see with reptiles are due to improper diet and/or husbandry. I would to know how long you have had them, what is their cage setup, what is the lighting/temperature/humidity set up, what diet have you been feeding, any supplements? How long were you gone? Etc. I don't have enough information to go on. ( https://www.lbah.com/reptile/chameleon-bone-disease/ ) Here is a list of reptile vets in PA. You will need to see if any are near you. You may have to drive a ways to find one..... ( https://www.thesprucepets.com/exotic-pet-veterinarians-in-pennsylvania-1239016 ) Hope this helps. If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.

Survey the area around the cage for any negative stimuli. This may include loud noises, strong vibrations, strong drafts or high traffic. Reduce or eliminate any if found. Confirm proper temperature. If it is too hot up high, he will move to cooler temps. Be sure to gut load prey for 24 hours prior to offering to maximize nutritional value. Dust with a calcium supplement as well as a multivitamin regularly. If the behavior persists, consider an exam with your vet or a vet experienced in treating reptiles to diagnose and treat illness or injury.

This sounds like metabolic bone disease. Very common symptom for this is loss of use of the back legs due to calcium deficiency. I doubt it has anything to do with him climbing around on you other than that activity used up the available calcium he had in his body. Are you sure your husbandry is 100% correct? Diet, lighting, temperature, supplements, etc. This is almost always due to improper husbandry. I suggest you review all of your husbandry and get him to a reptile vet for treatment.

Thanks for reaching out about Pablosita and including a photo. A veterinary visit is recommended in an attempt to determine spinal trauma vs. soft tissue trauma. Both conditions have a better prognosis is treated early. Calcium deficiencies can lead to weaker both more sensitive to trauma. Besides anti-inflammtories, acupuncture and other alternative medicine modalities could be beneficial. Good luck.

Haru needs to be examined by a veterinarian immediately. X-rays will likely be taken after a physical exam to diagnose any fractures or spinal injury. Soft tissue damage would have a better chance at recovery than a fractured spine. Only your vet can determine Haru's prognosis after an exam. Good luck.

Thanks for reaching out about the chameleon and including pictures. The first photo with the swayed back is very suspect of MBD/calcium deficiency. Diet and husbandry need to be review and correct, and a veterinary visit should be scheduled ASAP. Typically concerns are poor calcium in the diet, lac of UV light, poor temperature, etc. This is an emergency. Good luck.
