Hi there, I have been experiencing recurrent neck spasms, and shoulder pain, for about a year, and lower back pain on rising which has become increasingly painful, I also have the MTHFR A1298C polymorphism, generalised anxiety disorder, heart palpitations and regular head aches, alternating diahhroea and constipation, ongoing muscle twitching and fatigue.. recently I have been having muscle jerks too, I have had lots of blood tests, which show low iron, subclinical hyperthyroidism and am always told that I should go on antidepressants which I am not comfortable with. I had glandular fever shortly before my symptoms began approx 2 years ago and I m wondering if its possible that I have fibromyalgia? I also need to find a doctor that is familiar with the MTHFR as none I have seen thus far know about it yet.. I must find out if the doctors listed on this site bulk bill and see if I can get an appointment.. your thoughts are much appreciated. Kind regards
