Hello!

I have a madagascar jeweled lizard, I have had mine for about a month now. 
Shortly before I aquired the lizard I noticed it had a wound on it's tail infected with maggots, I was able to flush the wound and remove all of the maggots as I knew the store owner would not take him to a vet and I could not afford to purchase him. A few days later I was given the lizard. I was treating the wound with a topical spray and it was healing, until it started to form a large lump over it.

I immediately took him to the vet and they removed the lump and did a culture and determined that there was an infection of the bone.  We were treating him with regular baytril injections and a topical salve. At this point he still had feeling in all of the tail.

Well over the last few days the lump has returned despite treatment and his tail is starting to die off, he no longer has a feeling in the last 1/3 of the tail and it is dried and stiff.

He is at the vet now, but the doctor is not sure about amputation, I cannot remember why, I'm waiting for my mom to call me back once she has the chance to ask him. 

The doctor is also wondering if the lump is perhaps him trying to regenerate his tail, since the end of it is already dead perhaps?

I am not sure if this species drops their tails at all since there is not much information on them, I attempted to make him drop the tail at the beginning because of how deep/bad the initial wound was, but was unsuccessful.  

I would love some opinions if anyone has any, or if anyone knows if they do drop their tails or not...or if it's possible for them to attempt to regenerate a tail while their original tail is still attatched. I will provide more information as I come to know it, my mom works with the vet I take my animals to, so she is keeping me updated. 

I personally think that it is not a tail attempting to grow back because it's rising out of the old wound, and doesn't really look like it, it's back and leathery...and if that were the case there would have been bone when the first lump was removed? Also there was still feeling in the end of his tail when the first lump showed up....soo? I don't really know. Any help will be appreciated.

I will have more info as I learn it, and I will have a picture of the wound shortly.
