Hello, I understand how you feel. Within your age group this is not the common but I can tell you that this is absolutely normal if you are not having any associated symptoms like chest pain, breathlessness, giddiness, sweating of whole body, nausea. Or else it fine if you have all these because everyone's body isn't the same Some have excess sweating and all you need to do is to build up coconfidence In you in order to avoid these. Thank you
