Very interesting...I started with Tymlos for 15 wonderful months, no side effects and great increase in bone density, next I took 2 Prolia injections, no side effects from the injection but later I started feeling more aches and burning feelings in my hips and knees areas. Went to Reclast, as was told to take Tylenol the before, the day of and the day after. Day four my injection arm hurt for 2 weeks, couldn't bend my arm, on day 5 I woke up with pain and swelling in the bottom of my feet, I couldn't walk... Got Plantar fasciitis,2 months later I'm still in therapy. I hear some people that are small and weight around 104lbs had good doctors suggested 45 minutes infusion drips instead of 15 minutes that may help with side effects. Before consideing a FOREVER Prolia againI may consider taking Reclast again if I get some advice From some of you. Thank You
