About 4 days ago I acquired my first ever bearded dragon as a rescue he’s in pretty good shape, he just has a really big crack on his left arm and a growth under his neck, besides that he’s been ok he’s not eating as much but I’m guessing that relocation stress
Go here https://www.beardeddragon.org/useruploads/ and then to new upload. Select the photos you want to upload (one at a time). On mobile this is on the green menu button then select user image upload manager.
Then to post if you press XIMG then it should let you select from any of the uploaded photos.
I don't like the look of that yellow on the beard. I'd probably have a vet run a skin test to see what is causing that and treat accordingly. The elbow looks pretty bad but healed over. Is he having any trouble using the arm or putting weight on it? It looks like he's holding himself up on it which is a good sign.
Yea he uses the arm fine and he dosnt care if I touch it, and what could that big chunk on his neck be, and if it is a fungus are there any at home remedy’s
Possibly fungus or a cyst perhaps. Hard to tell for sure without having it tested which is a fairly simple procedure. You can put some antifungal cream like lamisil on it and see if that has an effect (it shouldn't hurt to try). There are oral antifungal meds that can be prescribed (voriconazole) to treat in conjunction with topical meds if the issue is determined to be fungal in nature.
