It get bigger and lumpy
Get bigger
No because it needs time to develop
The bump could be a cancerous tumor. If the bumps get larger, develop black scabs, and your hamster starts to poop blood this theory may be more or less correct. I am truly sorry about your hamster.
There are five common species of hamsters kept as pets: Syrian hamster, Dwarf Campbell Russian hamster, Dwarf Winter White Russian hamster, Chinese hamster, and Roborovski hamster. Each species has its own unique characteristics and care requirements.

Chances are, if it looks like your stereotypical hamster, it is a hamster. If it doesn't, it's a rabbit.
If you are extremely worried, I'd advise taking him to the vet to hear more details. However, if your hamster has sprained a leg, there is not much the vet can do. A cast can't be put around your hamster's leg as your hamster will just bite it off. The most advisable thing (this is what I did when my poor hamster sprained her ankle) is to take out any exercising equipment. Let your hamster rest his/her leg as long as possible, and maybe even spoil your hamster a bit by giving him/her extra treats to make up for stress that may develop as a result of he/she being unable to exercise and run around. The key is to wait it out, and give your hamster plenty of rest. Your hamster will recover in no time. ;)
