Most aches and pains aren't a sign of something serious, but certain symptoms should be checked out. See a doctor if you feel any of these things:

1. Weakness in Your Arms and Legs

If you get weak or numb in your arm, leg, or face, it can be a sign of a stroke, especially if it's on one side of your body.
You could also be having a stroke if you can't keep your balance, feel dizzy, or have trouble walking.
Get help quickly if you suddenly can't see well, get a bad headache, feel confused, or have problems speaking or understanding.
"Caught early, it is often reversible," says internist Jacob Teitelbaum, MD.
Don't wait to see a doctor. Call 911. If you get a clot-buster drug within 4.5 hours of your first symptom, you can lower your risk of long-term disability from stroke
