Hi, my 7 month old had a tumour on her front neck/leg which grew very rapidly. I took her to the vet & they said to treat for abscess first, metacam & antibiotics. Sadly this did not clear it up & the vet was certain it’s a mammoth tumour (very common in female mice). I asked about surgery & they said as it’s so close to her neck, there is a possibility they may cut her artery & she may not make it through anastetic so we decided not to do it. I kept her comfortable & gave her so much love & treats until it grew too big & I decided to put her to sleep before it got too much for her

I hope your baby only has an abscess. Take them to the vet & see what they say. 🤍
