Hi and thanks for the query,
Acute onset of pain in hand and leg, without any notion of trauma could somewhat demand for sure, an evaluation in an emergency setting. Other symptoms like fever, malaise
and any joint stiffness
could be helpful in making a diagnosis before then. The causes could range from inflammatory joint disease
, autoimmune disease
, infectious and other rare conditions. An evaluation by your primary care
physician, coupled with blood tests to evaluate inflammation, infection and X rays if need be could be very useful.
I do suggest you seek emergency care first to have a hold of the gravity of the situation. Thanks and kind regards as I wish you good health.
