I Have Been Taking Prolia For Several Years And Didn't

I have been taking Prolia for several years and didn't seem to have any side effects. For over a year now I have been having blood spots on my legs. They don't hurt but are ugly . About the time they go away, I get more. I haven't been able to have my legs exposed in the summer even. I have talked with my doctors and no one has an answer. Could it be the Prolia?
