Finding a new bruise on your arm or leg when you cannot remember bumping into anything can be concerning. If this happens frequently, you may start wondering: Why do I bruise so easily? Bruises are extremely common. Most develop after minor injuries that damage small blood vessels beneath the skin, sometimes from bumps so insignificant…

Everyone feels tired occasionally. A late night, stressful week, illness, demanding work schedule, or unusually strenuous workout can leave you wanting extra sleep. But what if you are tired all the time? Persistent fatigue is different from simply needing a good night’s sleep. Fatigue can feel like having very little physical or mental energy, struggling…

Waking up in the middle of the night because you need to urinate can be frustrating. For some people it happens occasionally after drinking a large amount of water before bed. For others, getting out of bed to urinate happens several times every night and begins interfering with sleep and daytime functioning. Frequent urination during…

Back pain is extremely common. It can happen after lifting something heavy, sitting for a long time, exercising, sleeping in an awkward position, or sometimes for no obvious reason at all. Fortunately, most episodes of back pain are not caused by a medical emergency. Muscle strains and other mechanical causes account for a large portion…

Feeling nauseous after eating can turn an ordinary meal into an uncomfortable experience. For some people, it happens only occasionally after eating too much or consuming a particularly rich meal. For others, nausea after meals happens repeatedly and may be accompanied by abdominal pain, bloating, heartburn, vomiting, dizziness, or feeling unusually full. There are many…

Finding a lump in your neck can be alarming, particularly when you are not sure how long it has been there or why it appeared. Fortunately, most swollen lymph nodes are caused by benign conditions, particularly infections, and many shrink again as the underlying illness improves.¹˒² Lymph nodes are small structures that form part of…

Feeling dizzy and lightheaded is common, but the word “dizzy” can mean very different things to different people. One person may mean that the room is spinning. Another may feel faint when standing up. Someone else may feel unsteady, weak, “off,” or as though they are walking on a boat. Those differences matter because dizziness…

Lower left abdominal pain can come from something as simple as constipation or intestinal gas, but the same area can also hurt with diverticulitis, kidney stones, urinary infections, bowel obstruction, reproductive-organ conditions, or other illnesses that require medical evaluation. The location provides an important clue, but it does not diagnose the problem by itself. Clinicians…

An itchy rash can appear suddenly, develop gradually, stay confined to one small area, or spread across much of the body. Sometimes the explanation is relatively simple—a new soap, dry skin, an insect bite, or exposure to an irritating plant. Other times, an itchy rash may result from eczema, hives, a fungal infection, scabies, a…

Chest pain can be frightening because many people immediately think of a heart attack. While chest pain should always be taken seriously, the good news is that many episodes of chest discomfort are caused by conditions that do not originate from the heart. The chest contains the heart, lungs, esophagus, muscles, ribs, cartilage, nerves, and…

Ear pain can be surprisingly uncomfortable. It may feel like a dull ache, pressure deep inside the ear, burning, fullness, or a sudden sharp pain that seems to come out of nowhere. Sometimes the cause is an ear infection, but an earache does not always mean something is wrong inside the ear itself. The medical…

Feeling winded after running, climbing several flights of stairs, or doing strenuous exercise can be completely normal. But what if you become short of breath while walking across a parking lot, doing housework, climbing a single flight of stairs, or performing activities that normally do not bother you? Shortness of breath with exertion—also called dyspnea…
