Patients can check symptoms to determine the cause of muscle pain in the legs by consulting with a medical professional and describing the type of pain experienced, explains Mayo Clinic. Extreme muscle pain in the legs that inhibits walking and produces fever or nausea should be evaluated in an emergency room setting.
A physician should be consulted when muscle pain in the legs causes swelling in both legs, the pain worsens, varicose veins are causing pain, or if patients have pain while or after walking, according to Mayo Clinic. Patients should also seek immediate medical care if symptoms such as redness, tenderness or warmth occurs within the legs or if a fever develops. Medical care is also necessary when patients experience breathing problems accompanied by swelling in the legs and calf pain after sitting for a prolonged length of time.
It is also important to evaluate potential causes for muscle pain in the legs, such as heat, dehydration or muscle fatigue, according to WebMD. Muscle cramps and leg pain are common among athletes who are not conditioned, endurance athletes and older people. Check symptoms with a physician, and detail any activity engaged in prior to the leg pain to determine if the cause of muscle pain can be attributed to injury.
