Uhm... usually childhood illnesses, measles, german measles, chickenpox, mumps.
Had them all... twice!!
Then nowt until I was 13.... I was bleeding internally, they never found out exactly why... but it caused me to be chronically anaemic with a blood count of 5.5 (for those of you who understand your blood count... you'll know that is pretty low). At first they thought I had leukaemia but was cleared after they took some bone marrow. They then believed it was something called a Meckel's Diverticulum... a remnant of structures within the fetal digestive tract that were not fully reabsorbed before birth. Approximately 2% of the population has a Meckel's diverticulum, but only a few develop symptoms. After several scans they still weren't sure, and decided it may have been a reactin to an aspirin... so I was discharged, the anaemia treated.. but never any the wiser as to why I had been passing blood.
Discovered I had a gall stone at 16.. went in for the operation, they did routine blood tests and found I had an over active parathyroid gland to go with it!!
So... ended up having two operations. One on my stomach, the other on my neck about 8 months apart.
Between the age of 13 and 17 I was in and out of hospital no end :-/
So.. yeah, guess you could say I was a bit of a sick kid all in all!
