Hello sir I'm here to inform you that as per my daily routine , I do a brick walk for 30 min and no pain during a brick walk and after brick walk running for 15 min but after running about 700 m pain happens in the chest, pain is like a bone pain, but continue running pain is gone... I did a TMT last month and the report was negative My highest pulse rate after running was 155 But after running and taking rest for 1/2 hour my pulse rate is still 94-96 Which type of pain is happening while running and  why my pulse rate is above 90 ?
