- Dramatic medical tales with predictable relapses

- Extensive medical knowledge and well read on the topic

- Have evidence of many scars

- Continue to complain of symptoms despite negative tests

- Very willing to undergo tests and surgery for minimal indications

- Seeking doctors in different cities and never willing to take family members to meet health professionals or vice versa
