I've been experiencing this really painful, pinching sharp heartache that makes it hard to breathe. It's mostly in the upper part of my left chest and lasts around 2 minutes. It's happened a couple of times even when I was on an empty stomach or just had some warm lemon water. I've had it at night before dinner too. I got some blood tests done, and they said my lymphocytes were high, but sugar was normal. I often feel short of breath while sitting too, and climbing stairs always makes me breathless. This month, its happened like three times. Do you have any ideas about what this could be?

Could be due to a condition called angina. Angina is chest pain or discomfort caused when your heart muscle doesn't get enough oxygen-rich blood. It may feel like pressure or squeezing in your chest. Given your symptoms and the fact that it has occurred multiple times, it is important to consult a healthcare professional for a proper evaluation and diagnosis. However, based on the information provided, you may benefit from taking medications such as Nitroglycerin sublingual tablets for immediate relief during episodes of chest pain. The usual dosage is 0.3 to 0.6 mg sublingually or chewed at the first sign of chest pain. Additionally, you may also be prescribed medications like Aspirin to prevent blood clot formation and reduce the risk of heart attack. The usual dosage is 75-325 mg once daily. It is important to follow up with a healthcare provider for further evaluation and management of your symptoms.
