I would definitely go see your primary care doctor
about this issue as soon as possible. You will need a complete physical examination to make sure that nothing serious is going on.
You mention that you have anxiety
, and certainly all of these symptoms that you are mentioning, such as pains in the chest and head, as well as racing pulse, could all be caused by anxiety.
However, the important thing when dealing with the possibility of physical symptoms caused by anxiety, is to make sure that they are not caused by something else! For example chest pains can be a sign of trouble with the heart.
Your doctor will be able to perform testing to rule out any serious underlying problem with your heart. Once this is done, if the diagnosis is that this is all related to anxiety, then your doctor will also be able to help you figure out what to do about that! Sometimes anxiety needs to be treated with medications, where as other times focusing on life style factors, like getting plenty of sleep and exercise, are all that is needed.
Start by setting up an appointment as soon as possible.
