These symptoms can have many causes, but kidney problems are among the possibilities.
## When Muscle Weakness Could Be a Warning Sign
Muscle weakness is common and often has harmless explanations.
Perhaps you’ve been inactive.
Maybe you haven’t slept well.
Perhaps you’ve recently increased your exercise.

– Significant swelling
– Changes in urination

– Recurrent muscle cramps
– Irregular heartbeat or palpitations
