[23M] Concerns about a long-standing lump and recent cardiac symptoms

What might be happening

Based on the information you've provided, here are some possible explanations for your symptoms:

• The lump above your Adam's apple: This could be a normal part of your anatomy, especially if it has been there since you were young and hasn't changed in size or caused any discomfort. However, it could also be a thyroid nodule or goiter, which are growths in the thyroid gland that are usually benign (non-cancerous). These are more common in women and older adults, but they can occur in anyone.

• Your episodes of heart racing, body shaking, and chest pain: These could be related to your Prolonged QT Syndrome, a condition that can cause fast, chaotic heartbeats. These rapid heartbeats might trigger a sudden fainting spell or seizure. In some cases, the heart can beat erratically for so long that it can cause sudden death. You should seek immediate medical attention if you experience heart palpitations or fainting spells.

What you can do

• For the lump above your Adam's apple: If it changes in size, causes discomfort, or if you develop new symptoms such as difficulty swallowing or changes in your voice, you should seek medical attention.

• For your episodes of heart racing, body shaking, and chest pain: It's important to manage your Prolonged QT Syndrome to prevent these episodes. This usually involves medication, such as the Nadolol you're currently taking. Avoiding triggers that might provoke heart arrhythmias is also important. These can include strenuous physical activity and stress. You should also avoid medications that can prolong the QT interval – there are many of these, including some antibiotics and antidepressants, so always check with your doctor or pharmacist.

What you should look out for

• If your lump changes in size or you develop new symptoms, you should seek medical attention.

• If you have a sudden, severe chest pain or shortness of breath, call 911 or go to the emergency room right away. These could be signs of a heart attack.

• If you have an episode of heart racing that doesn't go away on its own, or if you faint, you should also seek immediate medical attention.
