[SKB_Hamsters]

Unfortunately the photos aren’t showing for me. I would recommend taking you hamster to see a vet especially if a lump or bulge has formed in 2 days as it can be anything from tumour, to abscess or even organ failure (as this can cause fluid build up and can result in a bulge). The vet may be able to recommend a treatment plan or palliative care. Wish you and your hamster all the best.
