hello doctor my mother, in her late fifties, has complained of severe body aches since yesterday morning, so much so that she finds great difficulty to get up from bed or even lift anything using her fingers. and since afternoon today there has been an onset of mild but nagging fever which refuses to go down even after a dose of paracetamol. kindly throw some light on the possible reasons for this kind of a complaint and what can be done to relieve her of the pain and fever.
