Another distinctive sign of potassium deficiency is noticeable tingling or numbness in your hands, feet, toes, and fingers. This is a condition known as Paresthesia, in which you experience sensations without external stimuli. These are similar to the "pins and needles" feeling when your foot falls asleep, but are persistent or chronic versus caused by a specific way you're sitting.
Low levels of potassium can impact the nerve systems in your extremities. Chronic lack of potassium can cause this symptom. However, it is important to bear in mind that paresthesia is also connected to neurological disorders and nerve dysfunctions. If this is your only symptom of potassium deficiency then consulting with a specialist or your primary physician is critical to rule out a more serious medical condition.
