If he is getting adequate UVB lighting, a balanced diet and proper vitamin/mineral supplementation, then it may not be MBD. It could be trauma or infection.
Either way, he should be physically examined by your veterinarian or an experienced herp veterinarian to make the diagnosis. He may need treatment regardless of the underlying cause. Antibiotics may help infection, vitamin and mineral supplementation may help reverse MBD.

Have your herp veterinarian examine Nelson to rule out abscess (infection) or tumor. Make sure the UVB light source is not blocked by glass or plastic. Either blocks the beneficial rays. Position cage furniture so Nelson can bask 6-8 inches from the UVB source. Gut load prey for 24 hours before offering to Nelson to maximize nutritional value. Not all vitamin and mineral supplements are created equally. Herptivite and Reptile Calcium Powder with D3, both by Rep-Cal, are highly recommended.
If he's using his hind limbs and can get around normally, there is likely no cause for concern. Beardies are known to strike crazy and humorous poses. Laying that way may be comfortable for him. If he is having difficulty moving around, it can be addressed by your vet during the exam.

Why is my bearded dragon's tail crooked but she acts normal?

This could be an injury or very early MBD (metabolic bone disease). Have Harper examined by your veterinarian or an experienced herp vet for confirmation. Review her diet and vitamin/mineral supplementation regimen. If it is MBD, it can be corrected with just a few tweaks in diet and lighting. Check the age of the UVB bulb. If it is older than 6 months, replace it with a new bulb. You can review care and feeding of bearded dragons at the link below. http://www.anapsid.org/bearded.html

My bearded dragon has a back lump and can't move his legs. What's wrong?

Thanks for reaching out about Mushu and including pictures. You should be concerned and a veterinary visit is recommended. The lump on the back appears to involve the spine. The rear legs appear swollen and front legs held awkwardly. First thoughts are around metabolic bone disease, which arises from calcium deficiency, whether lack in diet, lack of absorption or lack of ultraviolet radiation. A veterinary visit can help with diagnosis and prognosis, provide injections of calcium and vitamin D3, and oral calcium supplements. Good luck.

My water dragon has MBD and tail issues. What should I do?

MBD can be treated, but Dobbie may never be "normal". Ideally, he should be physically examined by your veterinarian or a vet experienced in treating reptiles. If he has MBD, he likely has other issues related to poor husbandry and nutrition. Submit a stool sample to diagnose intestinal parasites. He may need antibiotics to help with the wound on his face. There maybe nothing to be done with the tail other than partial amputation if it is causing discomfort. Your vet can determine this after an exam. With the proper care and support, he can lead a close to normal life. You can review water dragon care at the link below. Kudos to you for rescuing the little guy! http://www.triciaswaterdragon.com/dragoncr.htm

Why is my bearded dragon's arm swollen? MBD, fracture, or infection?

It could be a fracture complicated by MBD but an exam and xrays is what Reptar needs to get a definitive diagnosis. It shouldn't cost "thousands". With proper care and some environmental and diet changes, he can recover from MBD. Left untreated, he may suffer permanent damage or even loss of the limb. An experienced herp vet will have the knowledge and experience to give Reptar the best chance at a full recovery. Follow the links to search for a local herp vet. http://www.herpvetconnection.com/calif.shtml http://www.anapsid.org/vets/findingvet.html

My bearded dragon has tail and foot injuries after cohabiting. Help!

While it is true that these signs could be due to trauma caused by the other beardie, it is also possible that it could be due to inappropriate nutrition or environment. Make sure that you are providing your bearded dragons with adequate calcium (supplemented in the food), and sufficient heat and UVB lighting in their cages. I also recommend that you take Luchi to see a reptile veterinarian in case he was injured and requires pain medications. You can find a reptile veterinarian in your area on www.arav.org.

Bearded dragon fell, swollen leg. MBD? Does he need vet & medicine?

MBD is possible but infections could be possible as well (causing arthritis). A check up would be ideal as the two differentials need to discriminated by a physical examination first before giving appropriate treatment.
