[|Human|] After an exercise routine like running in a park for 30 min, my hands are generally cold rather than warm. Although a recent ECG taken indicated no harm to my heart, I always feel discomfort on the upper part of the chest which is mostly indicated to Stress by physicians. I continuous feel worried about my heart. For sometime now, I feel difficult getting sleep in the night and feel fatigue during the day? Do you think this has anything to do with a Cardio problem
[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain and give you my opinion. You should know that heart pains have some Characteristics. They are usually retro-sternal pains likes quizzing, tightness or Heaviness. They may irradiate to both arms, neck and jaw. Furthermore, they last from 5 to 20 minutes and may be associated with tachycardia, difficulties in breathing deeply, anxiety. Pains that last all day long are not typical and usually are not related to heart. Felling tired might be related with a lot of pathologies like problems with heart function, anemia, electrolyte imbalances, thyroid gland problems. In my opinion you should not worry about. Your symptoms are not related to heart problems. Even though, to definitely know what is the problem if I was your treating doctor I will recommend some examination like a cardiac echo to evaluate heart function and walls, a holder rhythm monitoring to evaluate heart rhythm, a street test to exclude ischemic heart disease. A full blood analyze to exclude anemia, thyroid problems or electrolyte imbalance. Only after this we can better understand what we are dealing with. Hope I was helpful. Best regards
