Medicalstudentitis

I have a severe case of medicalstudentitis.  I have a runny nose, sneezing, coughing, lethargy and sulks.  But, rather than the common cold, I am suspecting many things, including TB, leukaemia and HIV seroconversion.  And I wouldn't dream of asking an actual doctor.  I'll just mutter darkly about my suspicions to medical student friends who will tell you about how they diagnosed themselves with Crohns and Behcets last time they got a mouth ulcer....
