Why does my female gecko have lumps in her armpits? Are they normal?

Thanks for using Petco Pet Education Center, formerly Petcoach! This may be due to a growth or perhaps an infection or inflammation. It would be best to have Goji evaluated by a veterinarian for further assessment and treatment. They would be able to sample this and determine what would be best to take care of it. Best of luck!

Your gecko may have a small abscess that has formed because of a wound/injury. If you are unable to take her to the vet just keep an eye on it for now. If it gets larger or causes Mica to not want to eat or drink, then you will need to have her checked out. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

Oh, your poor little Gecko! That's rough! Are you sure it is a female? The two things coming out the back end may be hemipenes as the males have two bulges on the underside fo the tale where their hemipenes are. If that is what is going on, it means a vet needs to try to put them back or or they may need to be amputated. Also, your little friend may need some anti inflammatory meds to reduce swelling after being stuck like that.

Ideally, a female crested gecko should be in the 35-40 gram weight range and at least 18 months old. If she's never been with a male, the eggs will be infertile. If she was previously mated, it is possible she may have retained sperm. Female cresties can retain sperm for 6 months or longer. A gravid female will typically lay just two eggs every month during breeding season. Egg binding can be characterized by. A swollen abdomen, lethargy, loss of appetite and frequent straining to lay. This condition should be addressed immediately by your veterinarian or an experienced herp vet.

The most likely diagnosis is going to be an abscess. Abscesses appear as hard tumor-like swellings. An abscess is an infected swollen area within body tissue, containing an accumulation of pus. The other option would be that this is a tumor. I suggest you get Pancake to your vet for an exam. Whether it is an abscess or a tumor, treatment from your vet will be needed. Hope this helps. Best wishes.

Keep an eye on it. It may be "normal" for your gecko or it could be localized trauma or infection. If it gets bigger or affects his eating, then have him examined by your veterinarian or a vet experienced in treating reptiles.

The area in question may be local irritation or infection. Monitor it for resolution or spread. It will likely disappear at the next shedding. If it gets worse or if Peaches develops lethargy or decreased appetite, then have her examined by your veterinarian or a vet experienced in treating reptiles to diagnose injury or infection.
