<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing some strange symptoms lately. I have been biting my nails a lot and my lips have been swelling. Also, Ive been having these odd sensations in my limbs, like a pins and needles feeling. And sometimes my elbows cramp up or spasm. Oh, and my memory has been really fuzzy too.  <response>: Based on your symptoms, it sounds like you may be experiencing factitious disorder. This is a condition where a person intentionally creates or exaggerates symptoms for attention or to assume the role of a patient. Its important to seek professional help to address this condition and any underlying psychological issues.
