She may have an infection in a tooth, jaw or mouth. If she will allow, check her cheek pouches for impaction. Hamsters will sometimes hoard food for so long that it will actually begin to rot in the mouth causing inflammation and infection. You can apply gentle pressure to get her to empty her pouches. They may need to be flushed with an antiseptic solution and she may need antibiotics or pain medication. Unfortunately, these medications must be dispensed by a veterinarian. A physical exam will be required in most instances before antibiotics or other prescription medications can be dispensed.

    This is usually caused by an infection of the cheek pocket and will require immediate check up to be confirmed and treated appropriately. Antibiotics will be required. If not complicated, in 7-10 days will be back to normal.
