Hello and welcome to Healthcare Magic. Thanks for your query.
It is possible that the symptoms which you are experiencing could be anxiety-related. Anxiety can manifest itself with not only psychological symptoms, but also with a variety of physical symptoms. Since, you also say that you are quite stressed out and do not have any known medical problems, this is a very likely possibility.
However, it is important to rule out other medical causes also. Thyroid
disorders, certain vitamin deficiencies, etc. can present with some of the symptoms which you have described. So, I would advise you to have a proper evaluation done by a doctor, in order to plan the further course of management.
Wish you all the best.
Dr. Jonas Sundarakumar
