Event Description
Within 24 hours of the synvisc i injection, on (b)(6) 2021, i was unable to independently walk, drive or navigate my home. I experienced extreme and significant swelling of the knee, debilitating pain and tremendous fear that the condition i wanted to correct was made far worse. Despite intensive icing, four days after the injection, i was prescribed prednisone, which i had no effect. Day six of the injection and after three days of prednisone (sunday), my husband took me to the emergency pain clinic operated by the orthopedic practice. I was examined, the dosage of prednisone increased, and i was fitted with a brace. Thursday, (b)(6) 2021, my treating physician, withdrew fluid from the knee along with synvisc for analysis and indicated i had an extremely rare reaction to the synvisc. Today, (b)(6) 2021, i still have great pain and simply seek a return to my pre-injection status, mild but tolerable knee discomfort. With synvisc i expected some discomfort - but no disability.
