I really hope that everythings ok with TS son.
Always check out these symptoms in a child but remember they don't always appear especialy in young children.
My dd aged 19 months who passed way to pneumococcal meningitis in April had no rash, no stiff neck , no aversion to light just high temperature, drowseness and vomiting the only time a doctor thought she had a something serious was when she had a fit which was 2 days after symptoms first appeared.
I will keep watching the thread for any news, i have my fingers crossed that all is well.
