Hi,
Sorry if this turns into a massive post......
I guess it's best to start at the beginning...about 9 months ago I had a really bad stomach bug and also had my mirena coil removed within a couple of days of each other (neither of these may be relevant but who knows?!). Since then I have had almost constant nausea, itchy palms and soles of feet (especially at night) and a really dry mouth. I have also noticed that I am going to the toilet more frequently (both urinating and bowel movements more often). I have become more and more tired over the last few months but cannot always sleep (never had a ny probelems like this before). Also noticed 'heavy' heartbeat at rest and been told at i have high heart rate and some arrythmia (inverted t waves on ecg). I have been tested for pretty much everything and some things have shown in blood tests have highlighted some levels outside of normal but I have been told that these are not clinically significant!! This is what I have been told is not quite right...
WBC, platelets, ferritin and folate levels low (but still around bottom level of normal)
MHC, cortisol and testosterone (SHBG) high but around upper levels of normal.
I have wondered abut thyroid issues but had two TSH levels done which came back 1.25 then 2.25 so I guess this is ok? Been told everything else is ok (including B12 as I did wonder about pernicious anaemia).
I have a really strong family history of autoimmune conditions (my dad and nan are both coeliac and we have graves disease and pernicious anaemia in both my parents families).
I have a heart scan on Monday and then go back to see my GP...Does anyone have any ideas? I think my GP has pretty much given up...but I am on the verge of having to leave my job and this is wrecking my whole life. I KNOW something is wrong and getting worse but just don't know what to do next

I have read loads on the boards here and there has been some really useful information...I am open to any suggestions anyone has!!!
Thank you so much for reading this
