Egg/chicken allergy: Synvisc (hylan g-f 20) reactions are either an inflammatory response locally in the knee or can be systemic if related to a chicken or egg allergy. If you suspect this may be the cause, consider seeing an allergist. Synvisc (hylan g-f 20) is derived from rooster comb, this the chicken and egg issue.

Unlikely, but possib: Unlikely, but possible. What was the reaction? Did it precipitate a gout attack or is there an infection?
