Bumps on Water Monitor

I have recently just bought a baby water monitor and I noticed there are two bumps on his spine it looks like they are part of it's spine because they are hard like bone is this normal I would apreciate the help

One of my skinks has Metabolic Bone Disease,this could be it but I am not sure if it can happen in monitors, MBD is usually caused by one simple thing: A lack of variety in the diet. Essentially, it comes down to a lack of calcium, and/or a Calcium/Phosphorus imbalance.

Hope that helps, good look!

Treatment
Treating MBD entirely depends upon what started it in the first place. To treat it, you have to KNOW what caused it. Whether it be poor conditions, no UV lighting (needed to metabolize calcium), or a terrible unbalanced diet, it's important to reverse whatever it is you were doing (or perhaps you acquired the animal in this condition). If you had an unbalanced diet, do your research and start feeding your animal the correct diet—one of course that is rich in calcium to bring balance back to the animal's system. If UV lighting is the case, take your animal outside often and let it soak in the hot sun. If there is no sun out, use a powerful fluorescent UV bulb. In the case of MBD, I would not rely on an incandescent bulb as many claim UV rays which they might not have. A common question asked is if MBD is reversible. The answer is that it's not reversible per se, but definitely treatable

No offense but please do not try to give a diagnosis over the internet 1) without being a licensed vet 2) seeing the animal.

Take the monitor to a reptile vet and have it checked out and x-rays performed of the affected area(s). Could be MBD, could be tumors or even cancer. You just don't know. Could even be a calcium deposit or bone over growth from a previous break /injury. You just don't know and shouldn't guess.

Head to the vet.

Oh an the only monitor species that requires UV lighting is acanthurus (aka Ackie).

I know, I am just trying to help.
