Unusual Problem: The clue that the symptoms occur only when driving suggest a connection to arm exercise.

See doctor asap: If you are talking about tylenol, (acetaminophen) it is much more toxic in someone who is drinking that much, and if he takes 8-10 day he may be causing liver damage. If you are talking about Ibuprofen (motrin, advil) or naproxyn (alleve), it can cause stomach, liver and kidney damage, particularly when combined with alcohol. See a doctor for an evaluation as soon as possible. Read more

Not an issue: Your heart speeds up or slows down in response to various factors. The main factor at your age is hormones that are part of the stress response, it prepares your body to run if chased by a bear, etc. The teen years are stressful, and periodic rapid heart rate is expected. You sound pretty normal and the rate of any heart condition is so rare at your age I can't see it happening. Read more

I am experiencing shaking hands or tremor, lightheadedness (worsened by: prolonged standing) and leg tingling. & can hear my own heart beat?

Anxiety symptoms: My first guess is that you are anxious. And you are breathing fast during the spells which makes you blow off CO2 and can lead to the symptoms you describe especially the tingling. Try rebreathing into a paper bag so CO2 returns to normal for a few minutes. If this helps bingo. Discuss with your Dr. Read more

Possible hypoglycemi: Low blood sugar can cause these symptoms. Reactive Hypoglycemia can result from eating carbohydrates which raises the blood sugar which then causes a release of insulin which, in some cases, lowers the blood sugar too low bringing on the symptoms mentioned above. Blood testing can diagnose hypoglycemia at the time of symptoms or a few hours after eating a carbohydrate load. Discuss with your MD. Read more

Chest symptoms: The symptoms you describe do not necessarily indicate a particular diagnosis. Central left chest pain can be a symptom of serious conditions and it is always better to be safe than to ignore it. You don't want to miss a cardiac problem. Consider seeing an internist or cardiologist, or an Inbox Consult on HealthTap. These little text boxes are too small for a detailed review of your history. Read more
