My husband has commenced treatment with fosamax five weeks ago. He had recently been diagnosed with osteopenia; he suffered a compression fracture of his L1 vertebra in 2010, and also has widespread degenerative disease in his lumbar spine. In the past couple of weeks he has complained of much more severe back pain than usual, which hasn't responded to any tried analgesia as yet. Could this increase in pain possibly be connected to the fosamax? He is 75 and is taking 70/70 once weekly.
