My son is 18, he’s always been very active and since finishing his exams has started training hard at the gym. A couple of things are concerning me, he is getting chest pain during and after exercise, which I know could be caused by a number of things and when he is on the treadmill his heart rate is going up to 190bmp which seems a lot but might be totally normal when pushing hard.
There is a history of heart disease in my husband’s family and I think given what’s happening when he exercises he should get himself checked out. He doesn’t think it’s necessary, so am I being unreasonable?
