[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. Possibility of anemia or vitamin B 12 deficiencies is more. In both these conditions, discomfort in chest (palpitations, thumping, twitching) on exertion is seen. And at your age heart diseases are extremely uncommon. So better to get done hemoglobin estimation and vitamin B 12 level. If deficiency then you need supplements. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
