"Got severe side-effect from taking Boniva (150mg monthly) for 3 months. Crippling, debilitating bone-joint pain at the hip. Very stiff sensation at the chest sternum and ribs. Went to Urgent Care twice. Flat on bed for 2 months with intense pain and prescribed pain killers (hydrocodone/Dilaudid, prednisone, etc.) have no effect. Discontinue taking Boniva and the pain subsides after three months. Three doctors don't believe it is the Boniva side effect until the fourth MD specialist, a rheumatologist recognizes the Boniva side effect symptoms after a long differential diagnostic (she also has two previous patients with similar symptoms after taking Boniva).
