Hello and welcome to Healthcare Magic. Thanks for your query.
Your boyfriend's symptoms could be anxiety-related. Anxiety can manifest itself with not only psychological symptoms, but with physical symptoms also. However, the first step is a thorough medical evaluation to rule out ant possible medical problems. Once this is done then, he can consult a psychiatrist
for a detailed psychological assessment and further treatment of his anxiety / stress
Wish you all the best.
