Hi, I have been an active 55yr runner, doing a marathon in April this year I treated myself to a Fitbit Charge 2 HR. Slowly over 10 weeks? Not sure exactly how long but I developed swollen wrist on worn side, that gradually became sore and stiff then almost overnight my legs and arms at night just became stiff and odd feeling. I took off Fitbit and very slowly it improved until it slowed and left with nighttime stiffness and awful hip and shoulder pain. Diagnosis PMR with esr 47. Put on Pred 15mg x5mg x3 daily. I’ve taken 5 tabs and already huge improvement. I’m just not convinced it’s PMR but whole body inflammation from Fitbit which I can’t prove. Now after reading I’m really concerned about taking these meds. Any thoughts? At 55kg NICE dose is 10mg? Daily. Feeling overwhelmed. Thank you for any advise.
