Diagnose disease from unusual pain

The pain appears suddenly and is often accompanied by a number of dangerous symptoms that need attention, according toReader's Digest.

Sudden headache

If your headache comes on suddenly and is so bad that it becomes unbearable, you may have a brain aneurysm. If left untreated, the blood vessel can burst, leading to a stroke, which can be fatal, or a brain hemorrhage.

Toothache when drinking cold drinks

Damaged enamel (the outer layer of the tooth) or decay can expose the nerve inside. You experience pain when this area comes into contact with anything cold or hot.

Additionally, an exposed nerve also puts you at risk of bacterial infection and spreading it to other parts of your body. See your dentist for a check-up if you experience this symptom frequently.

Pain in the hand, wrist, and forearm

If pain or numbness occurs in the hand, especially in the thumb, index and middle finger, palm, wrist and radiates to the forearm, you may have carpal tunnel syndrome.

If left untreated, the hand muscles will contract and even lose mobility, experts warn.

Chest pain

This is a classic sign of a heart attack, due to lack of oxygen to the heart. The pain may also move toward your jaw, shoulder, or neck.

Dull pain in the middle of the back

If the pain gets worse and is accompanied by fever and nausea, you may have a kidney infection. An infection can cause permanent kidney damage, blood poisoning, or complete kidney failure.

When pain travels down the lower back and affects the leg, it is a sign of sciatica, caused by injury or pressure on the sciatic nerve. If you have leg pain, loss of bladder sensation, or incontinence, you may have cauda equina syndrome, a rare disorder that causes permanent paralysis.

Pain in the lower right side of the intestine

If you have a fever, nausea, or vomiting, you may have appendicitis. A ruptured appendix can lead to a potentially life-threatening infection, so you need to get to the hospital right away.

Pain in the pelvis or abdomen

Menstrual cramps are normal for many women. If the pain gets worse or doesn't go away, you may have endometriosis.

Pain or cramps in the legs

If the pain is accompanied by redness, warmth, and swelling, you may have a blood clot called deep vein thrombosis. Do not massage the painful area as this could cause the clot to travel to your heart or lungs.

In addition, the feet are numb, burning, you may have nerve damage due to diabetes causing loss of feeling in the feet. In the late stages, the patient may have to amputate the foot to prevent the disease from progressing.
