My arm hurts from my last COVID? vaccination.

Hello, thank you for your question!

No, Naproxen does not contain penicillin. You can take it for pain relief (if you don't have any contraindications or allergies to anti-inflammatory drugs), in addition to applying ice in a wet bag or towel for 10-15 minutes at a time.

I hope this has been helpful to you, and if you have any further questions, please don't hesitate to ask!
