Without seeing the lump, it's hard to say what it might be. Some possibilities would include a localized bacterial or fungal infection, a local inflammatory reaction due to an insect bite or sting, a lick granuloma (causing by excessive licking), or even a skin tumor of some kind. I would recommend having the lump examined by a vet when you are able to - he/she can do some testing if needed to help determine what it is and what treatment is needed.
