the feeling ofloss of strength in a limb can occur progressively or suddenly. Sometimes it happens in the upper limbs, in the lower limbs, or even in the arm and leg one side of the body.

 

When the loss of strength occurs abruptly, one can think of a vascular event, such as a stroke. This should always be ruled out and an evaluation by a specialist doctor, such as a neurologist, is often enough to exclude a serious illness, almost always without the need for a complementary exam.
