What is the effect of medical terminology on communication between healthcare providers and patients?

Yes, the use of medical terminology may make the patient perceive their condition as more serious than it is. For instance, nailbiting may sound dangerous when referred to as onychophagia. Lichenification or neurodermatitis sound more serious than "rough skin due to itching". In addition, some terms can cause distress because they may be perceived as a personal failing rather than a medical condition. Examples are "habitual abortion" for frequent miscarriage, or "incompetent cervix" for a cervix that opens early during pregnancy.
