Sherry, Good question. One of the common symptoms of asthma is a chest tightness, a feeling that you can't really get a full breath in or out. If this is what you mean by your chest hurting, then yes, it is probably your asthma. If it is more of an actual pain, then that might be something else, such as something with your heart.
Likewise, if your asthma is not well-controlled, then you might feel tired and low on energy. But you should not feel that way if your asthma is under control. So, if asthma is controlled, but you're still feeling tired, again, it could be something else.
My advice is to discuss your concerns with your doctor who knows you and your medical history. Make sure there isn't something else going on that needs to be treated.
