My hamster's tail has a red blister. Is it a bite or infection?

Pet's info: Small Animal | Hamster | Female | unspayed | 10 months and 22 days old

My Syrian hamster's tail has a red mark at the tip. It looks like a red blister. I heard her make a distressing noise when she was in her bed earlier in the evening. I'm wondering if she accidentally bit her tail.She's behaving normally and I touched her tail and she didn't react.

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths.
