Help!

Question
My hampster shoulder is swollen and i dont know why..i see no bruises or anything..plz help..

Answer
Hi Anthony

Whereabouts is he swollen?  Is his whole body, or is it just one area?  What type of hamster is he?  How old is he?  Apart from this how is he behaving? Has anything changed in his surroundings - any new bedding etc?  Has anything been sprayed near the cage?  Is he bright in himself and eating normally?

If you want to give me a few more details I might be able to suggest what is wrong.

Regards
