Gosh this is really scary. My endocrinologist just had a conversation with me about possibly taking Reclast. I asked her what the side effects are and she said you can feel unwell for 24 hours or so and in rare cases you can get the haw problems. However, I have a kidney disease and she said Reclast can impact the kidneys. Do you currently have osteoporosis or osteopenia? I ask because I have osteopenia and we discussed the option of waiting another year or going on Fosamax or some other pill option.
