If you look in the mirror and see a red spot in the white of your eye, it could be a broken blood vessel. If so, you may have had a subconjunctival hemorrhage, which happens when a tiny blood vessel breaks just underneath the clear surface of your eye.
This can be completely harmless but you should still see a physician to make sure there is nothing more serious at play.
Few heart attacks look like they do in the movies – a person grabbing their chest in pain and collapsing. Instead, heart attacks may present themselves through symptoms like heartburn or nausea. Although nausea can be a symptom of many different things, if it is particularly intense and sudden, you could be having a heart attack.
Nausea is also a symptom of certain types of cancer, such as liver cancer or stomach cancer. Be sure you visit a doctor if you have nausea or heartburn and can’t pinpoint a cause, or if it comes and goes.
#18 Sudden Weakness
There are many hidden signs of a stroke, including experiencing sudden weakness, and they should prompt you to see a doctor immediately. When you feel sudden weakness in an arm, leg, or numbness in your face, these are all signs of a stroke.
Even mild strokes can provoke weakness in the body, so it’s important to take these symptoms seriously.
#17 Loss of Interest in Food
Gall bladder disease can cause nausea, vomiting, abdominal pain and a feeling of fullness. One of the lesser known symptoms of gall bladder problems is a loss of interest in food.
This is because when the gall bladder is infected, people experience feelings of sickness after meals, then their emotions adjust and they begin to avoid food. If indigestion causes you to lose your appetite, contact a physician.
#16 Persistent Cough
A persistent cough should not be dismissed as simply a minor irritation. It could be a sign of lung cancer, even in people who don’t smoke. If you smoke and have a cough, see a doctor to find out whether or not your cough is a symptom of lung cancer.
If you don’t smoke and can’t get rid of a cough, you should see a doctor as well. The majority of lung cancers in non-smokers occur in women.
