I wouldn't let that knock you down Suzy.
For year's my Girlfreind has been ill, they told her for year's she had migraine head ache's, and guess what every doctor read the first page of her notes and didn't read any further than the word 'migraine'. i have sat in with her on many appointments in gp's, by her hosptital bed, whilst she fitted on the floor in my house and blue lighted in the back of a ambulance several times too a hospital. and it turned out too be Not headache's at all.
And guess what??.
My m.r.i came back normal too and the blood tests as well, just like many folks.
we have good day's dont we, we have bad days.
Stick at it Suzy and dont take that for a Answer.
