@carolgrandma I see that you expressed, “ first of three”. It is my suggestion that you decline any additional Reclast infusions unless your endocrinologist can provide you with the answer you seek! I am a 69 year old male who received his first and last infusion two plus years ago. Much like you, I was quite physical and had your normal aches and pains. After the infusion I too had flu like symptoms at first and after about a week, bang ‼️ shoulders, left foot, vision, lower back, hips, weak muscles and nausea to mention just a few. My Endocrinologist said, “ this is not from the infusion “ and suggested I see a rheumatologist, who suggested I see a Neurologist who suggested I see my Endocrinologist. No one can explain my symptoms! I’ve been going to physical therapy bi-weekly since my infusion. Three suggestions! Look up Reclast infusion and potential side effects, contact FDA to report your symptoms and take care of yourself! I apologize for not having better answers and should you find a solution I would truly appreciate your feed back!
