Allergy Injection Site

Patient: I get allergy shots weekly for my allergies to grass, weeds, and trees. This week we upped my dosage. I have been itching one of my shot locations a lot. It is now a large hard bump, red, hurts, and still itches. My nose is also itching and I’m experiencing slight stomach cramps. Is this anything to be concerned about?

Symptoms: Itching, redness, pain, swelling
