I have had warty skin eruptions on the joints of my fingers. My dermatologist has given a preliminary diagnosis of perforating disorder and thinks it may be due to fosamz. Since the drug is changing metabolism - he is suggesting that these lesions are erupting from near the joints. Has anyone on Fosamax had warty like skin eruptions over the joints of your fingers? I do not like taking this drug. I have taken it 11 months.
