Why does my hamster have a hug lump on her shoulder? She is doing her normal activities and she looks like she isn’t in pain. A few days ago she didn’t have that lump. Why does she have it now? What happened to her?

I am sorry to hear about your hamster. With a swelling like this we would worry about a variety of problems including a cellulitis or inflammation/infection of the tissues, swelling due to trauma like a broken bone, swelling due to edema or disruption of lymph flow, or unfortunately a tumor. I would recommend having a veterinarian examine your hamster to determine the source of the swelling and the possible treatment options.
