Definitely! There are a whole bunch of symptoms that can show up at any time. Bear in mind that the longer your anxiety goes on the more symptoms you will most likely have. You will probably even experience them when you are calm. The body takes time to recover from frequent or prolonged anxiety and so you can experience these things for some time after you stop being anxious which is what you want to be aiming for. As I said you should go to the doctor, get yourself checked and all clear, tell them about the anxiety and start your recovery. Constantly seeking reassurance isn't going to solve the problem.
