[|Human|] Hi. I am 25 years old. Remain very tired and feel sensations in my body. Get tired soon after taking stairs and the Heart throbs for a day if I run at full pace. I dont smoke and drink. there is some pressure on heart but I have got all that tested. Everything seems fine (including echocardiogram). Could this be a problem with lungs, cancer?
[|AI|]  Hi and welcome to Chat Doctor. No, but it can be anxiety because you think you might have cancer. How can you even think of lung cancer if not smoking and are 25 years old.:) Good that you've checked your heart, but did you check your thyroid, lungs and estrogen and iron levels? These are the most common causes of symptoms you're mentioning. So do ventilation tests and other 3 i ve said, and I am sure you'll find exact cause and be able to treat it successfully. Wish you good health.
