11. Flu Symptoms
If you experience symptoms associated with the flu outside of flu season, and they don’t go away over time, it could mean that you have a chronic condition like Lyme disease.
12. Pain in the Heel
Heel pain is an expected side effect of working on your feet all day, but those who don’t perform such work but still feel heel pain might have a more serious issue. Back problems can often be felt in the heel.
13. Smell Sense Loss
As you age, your sense of smell will gradually weaken, but if it happens all at once or over a period of just a few days, it could be a sign of a more serious problem like Alzheimer’s disease.
14. Widened Eye Veins
The veins in your eyes are a precursor for vein activity in your brain, so if they suddenly grow larger and stay that way, you should consult a doctor. This could be a sign of dementia or even something as simple as high blood pressure.
15. Urge To Eat Ice
A lot of people chew on ice chips for the occasional calorie-free snack, but those who constantly feel compelled to eat ice might be suffering from anemia. In some cases, it could even be a sign of pica, which is the urge to eat anything that isn’t food, like paper or sand.
