In general, there are a variety of reasons that can cause bumps to be in the back of the throat. Infection would be the most common, including a variety of viral issues. If this is the case, they normally spontaneously resolve.
Bacterial infections, like strep, can also cause bump-like lesions. If suspected, a throat culture can be obtained.
Going to your personal physician, or in refractory cases, an ENT specialist, would be the next appropriate step.
