Some examples of symptoms that need to be checked by a physician include inability to keep fluids down, unexplained weight loss, dizziness and feeling tired all the time, as stated by Merck Manual. Those with other medical conditions or the very young or old should err on the side of caution and have any unusual symptoms evaluated as soon as possible.
In general, it is best to have the patient's regular doctor perform the evaluation because that doctor will be familiar with the patient's medical history, but stat cares and emergency rooms may also be needed, according to the Center for Advancing Health. Excessive pain or swelling around an injury site may be cause to have the patient evaluated at an emergency care clinic for a sprain or possible broken bone. Loss of consciousness, seizures, feeling short of breath, heart palpitations or any symptoms of a heart attack or stroke mean the patient needs to be taken to the emergency department right away.
The elderly may find it harder to decide when to go to the doctor for nagging symptoms because they often interpret them as normal signs of aging. Experiencing abdominal pain, bloody stools or trouble using the bathroom indicate that the patient needs to be seen by a doctor as soon as possible.
