Is it normal to experience joint pain after allergic reaction?

Yes: Yes, certain types of allergic reactions can cause swelling of tissues and joints (the medical term for this type of reaction is "serum sickness"). One can experience joint pains in such reactions. Ordinary allergic conditions like nasal and eye allergies are not associated with joint pains unless you have other concomitant condition like fever resulting from a viral or bacterial infection.
