Can arthritis in neck and shoulders be the cause of "positional vertigo?" In the past, when I've experienced vertigo symptoms I've visited my chiropractor for an adjustment that would successfully relieve my misalignment, which was pinching a nerve in my neck and causing the dizziness. My last episode was not as successful, though.

Dyspnea is the technical word for difficulty breathing. It's a common symptom in people who have lung cancer or have cancer that has spread to the lungs. People who experience dyspnea describe it as difficulty in breathing or shortness of breath. They often compare it to feeling like they are suffocating or being smothered. In many cases, patients may develop anxiety or panic if they feel they cannot breathe. Often their anxiety and fears can make the dyspnea worse. By panicking, patients can become more breathless and begin a cycle that is hard to stop.

Detailed information on the most common breathing problems in a newborn Babies breathe much faster than older children and adults. A newborn's normal breathing rate is about 40 times each minute. This may slow to 20 to 40 times per minute when the baby is sleeping. The pattern of breathing in a baby may also be different. A baby may breathe fast several times, then have a brief rest for less than 10 seconds, than breathe again. This is often called periodic breathing and is a normal occurrence. Babies normally use their diaphragm (the large muscle below the lungs) for breathing.

Severe shortness of breath and shortness of breath accompanied by certain symptoms requires immediate medical attention.
|
|
If your child cannot seem to get enough breath in his lungs (shortness of breath) or is having a hard time breathing, he probably has a medical condition that needs treatment. If your child is old enough to talk, he can tell you that he is having difficulty breathing. If your child is younger, you may notice that he is breathing harder or faster than usual, isn't feeding well, or is cranky.

I had a quadruple bypass seven years ago. A few months back I found myself taking frequent short breaths when I climbed the stairs. Once I stopped exerting myself, my breathing soon returned to normal. Is this due to a problem with my heart or lungs?
|
|
For the past two months I have experienced increased shortness of breath. I have chronic asthma, but there's concern the shortness of breath could be caused by a blockage in heart. I have experienced difficulties in the past when anesthetized. Is there an effective alternative to heart catheterization? I've read about a new CT scan ? is it recommended?

Shortness of breath may be a warning sign of heart disease.
Chest pain is a near-universal signal of heart disease. Shortness of breath may be an equally valuable tip-off.

If your blood pressure drops too low, your brain may not get enough oxygen-rich blood. Your body responds by losing consciousness briefly. You also slump or fall down. This problem is called syncope, fainting, or a blackout.

When the brain receives conflicting signals, or when there is a problem with blood flow, dizziness or fainting can occur.

Syncope, or fainting, is a temporary loss of consciousness, usually caused by decreased blood flow to the brain. Syncope is a symptom, rather than a disease itself, and has many causes.
|
|
Fainting is a loss of consciousness, falling down or needing to lie down, followed by spontaneous recovery. Fainting by itself is not a problem, but it could be a sign of a serious health condition.

Every time I have blood drawn, I have vasovagal reaction. Does that prevent me from blood donation? Any advice how to combat this?

Electrical system problems of the heart may make the atria beat faster than normal. If the atria beat quickly, but still evenly, it is called atrial flutter. If the atria beat very quickly and unevenly, it is called atrial fibrillation.

Doctors often consider chronically low blood pressure too low only if it drops suddenly or causes noticeable symptoms.

While recommended healthy blood pressure levels have decreased, lowering diastolic pressure too much could deprive the heart of needed blood flow, which could be dangerous for people with coronary artery disease.

Preliminary studies show that a promising new drug may treat the symptoms of low blood pressure.
