6 SERIOUS MEDICAL SYMPTONS SHOULD NEVER BE IGNORED.

1. Paralysis of the arms or legs, tingling, numbness, confusion, dizziness, double vision, slurred speech, trouble finding words, or weakness, especially on one side of the face or body.
These are signs of stroke -- or a "brain attack" -- in which arteries that supply oxygen to the brain become blocked or rupture, causing brain tissue to die.
Symptoms depend on which area of the brain is involved. If a large blood vessel is blocked, a wide area may be affected, so a person may have paralysis on one side of the body and lose other functions, such as speech and understanding. If a smaller vessel is blocked, paralysis may remain limited to an arm or leg, or even the face.
If you have symptoms, call Ambulace or go in Car right away and get to an emergency room that offers clot-busting therapy for strokes due to blocked vessels. Such treatment, which dissolves clots in blocked vessels, needs to be given within the first 3 hours after symptoms begin, but newer treatments may work within a longer time frame, says Birge, who is medical director at the Tanner Medical Center in Carrollton, Ga.
Timing is urgent; fast treatment can potentially stop brain tissue death before permanent brain injury happens. "There is a time clock ticking as to when you might totally recover.

2. Chest pain or discomfort; pain in the arm, jaw, or neck; breaking out in a cold sweat; extreme weakness; nausea; vomiting; feeling faint; or being short of breath.
These are signs of heart attack. If you get some of these symptoms, immediately go to the emergency room by ambulance or Car. It is also recommend that patients chew one regular, full-strength aspirin (unless they're allergic to aspirin) to help prevent damage to the heart muscle during a heart attack.
Not everyone who has a heart attack feels chest pain or pressure or a sense of indigestion. Some people, especially women, the elderly, and people with diabetes, get "painless" heart attacks, the doctors say. Being aware of "painless" heart attack signs is crucial: symptoms may include weakness, sudden dizziness, a pounding heart, shortness of breath, heavy sweating, a feeling of impending doom, nausea, and vomiting.

3. Tenderness and pain in the back of your lower leg, chest pain, shortness of breath, or coughing up blood.
These are symptoms of a potentially dangerous blood clot in your leg, especially if they come after you've been sitting for a long time, such as on an airplane or during a long car trip. These signs can also surface if you've been bedridden after surgery.
"Anybody is susceptible," Birge says. He adds that such blood clots are more common than most people and doctors realize.
Blood is more likely to pool in your legs when you're sitting or lying down for long periods of time, as opposed to standing and walking. If a blood clot forms in your leg as a result, your calf can feel swollen, painful, and tender to the touch. If you get sudden chest pain or shortness of breath, a piece of the blood clot may have broken off and traveled through the bloodstream to your lungs. This condition can be life-threatening, so get to an emergency room without delay if you have any of these symptoms.

4. Blood in the urine without accompanying pain.
Anytime you see blood in your urine, call your doctor promptly, even if you have no pain.
Kidney stones or a bladder or prostate infection are common causes of blood in the urine. But these problems are usually painful or uncomfortable, which sends people to the doctor promptly.
In contrast, when people see blood in their urine but feel no pain, some take a "wait and see" approach, especially if they just have one episode. "But you can't have this attitude," Lack of pain doesn't necessarily mean lack of seriousness.
Cancer of the kidney, ureter, bladder, or prostate can cause bleeding into the urinary tract; when these cancers are small enough to be curable, they may not cause pain. So don't dismiss this important sign because. "blood in the urine may be the only clue for an early diagnosis."
5. Asthma symptoms that don't improve or get worse.
Asthma attacks are marked by wheezing or difficulty breathing. When an attack doesn't improve or worsens, a patient should get emergency care.
If an asthma attack is left untreated, it can lead to severe chest muscle fatigue and death. Some people with persistent asthma hesitate to go to the emergency room because they've gone so many times before, or they need someone to drive them because they're too short of breath. So instead of seeking care, "They try to hang in there, even if they need higher doses of inhalants or have decreasing lung function measurements when using a device to measure how well they move air out of their lungs.
Because asthma makes breathing difficult, the muscles for breathing may tire and the volume of air exchanged by the lungs will decrease. As a result, a person's oxygen level drops while blood levels of carbon dioxide rise. "A carbon dioxide buildup in the blood has a sedating effect on the brain, which may cause you to feel even drowsier. You may lose the motivation or energy to breathe."
"A person with asthma who seems to be relaxing more, who seems to not be struggling for breath anymore -- even though they've been at it for 6 or 8 hours -- may actually be worse. It could be a sign of respiratory fatigue." Eventually, the person could stop breathing.

6. Depression and suicidal thoughts.
Few people would put up with crushing chest pain or extreme shortness of breath, but many endure depression, even though, at its extreme, it can be life-threatening.
"Depression can be a very, very serious problem because people can commit suicide. "Some people will not seek care when they are depressed because they think that they'll be perceived as being crazy or not strong or not manly, and they have to understand that there is a chemical imbalance going on in their brain. It is a disease just like any other disease."
Symptoms of depression include sadness, fatigue, apathy, anxiety, changes in sleep habits, and loss of appetite. Depression can be treated with medications and psychotherapy. more
