Hi APH and welcome.
I am so sorry that you are currently going through this scary and confusing experience.
However, I am glad that you have reached out to us, and have received some good advice and comfort...that is what this community is all about
It is good that you have an upcoming appointment. That is always the first step that you want to take...to get checked out physically. However, considering your age, and that you have no obvious risk factors (I am assuming)...you are likely dealing with anxiety.
However, as you rule anything organic out at your visit with the doctor...you will also be able to discuss treatment options such as therapy and/or medication...a win-win.:)
If you feel that you need to be seen before your scheduled appointment ...if your symptoms increase, or you simply feel that you need immediated medical attention, then I do suggest that you go with your idea of being seen at the Urgent Care as a precaution.
For now, I am going to give you the link to our Resources here. You will find stress relieving exercise instuctions that will help relieve the anxiety and symptoms, as well as other great ideas and information.
Keep posting with us. We understand, care and are here to walk along this journey with you as you seek recovery.
