My arm hurts.

Allergy shots are becoming less fun these days. Not that they ever were, but they're definitely worse now. I'm not yet receiving any of the benefits, but I sure am feeling the downside. I'm starting to regularly now react to my shots. It starts out as a painful little bump, which then spreads across my upper arm. For several days it itches and is slightly painful. The one last week actually left a bruise. Needless to say, I am not enjoying today's shot either.
