Muscle cramps typically resolve on their own. But if cramps cause you extreme pain, happen frequently without an obvious cause or occur with other symptoms like muscle weakness, swelling or a change in skin color, visit your doctor, per the Mayo Clinic.
Most electrolyte imbalances are temporary and can be resolved by hydrating and eating nutrient-rich foods. But if you notice symptoms like nausea, vomiting, confusion, seizures, or you lose consciousness, get medical care immediately, as you may be experiencing a severe sodium deficiency, per the Mayo Clinic.
Use this equation to determine how much water you should drink every day: Body weight (in pounds) ÷ 2 = minimum ounces of water you should drink per day
Body weight (in pounds) ÷ 2 = minimum ounces of water you should drink per day
Though you may have heard that vitamin E can help treat leg cramps at night, there’s not much recent research to support this claim, per a May 2015 review in BMJ Clinical Evidence.
