I am terrified and feel sick.  I am a single Mum with a son about to turn 2 in 5 weeks.   My sister died suddenly out jogging with her toddler in June.   Since then I have been having heart tests as a precaution including a cardiac CT scan a couple of weeks ago.    Just an hour ago get a call from my local hospital saying a general CT scan (not heart as I asked) has been requested and could I come in tomorrow?!!!!!    She didn't say who had requested it or why so I am terrified.    I am worried my chest one has shown up lymph nodes and they are trying to find out why.     

I cannot be ill as I am a single Mum with no one to look after my son if ill or worse.   I have convinced myself I'll be told I have cancer tomorrow.    I am a mess and my son can tell something is wrong as I'm crying and shouting as scared .    I shouldn't be watching Coronation Street this week .  

I've had frequent urination, pain in abdomen and back, acid, pain running down front left thigh for months but just get told be a trapped nerve and here is some painkillers  

Could be not cancer related? I don't know
