Dx with Intestinal Small Bowell Chrons Disease in Jul 2011 - costisteroid treatment 6 months. i then developed symptoms of heat/burn over upper back, disorientation, drop in sugar/BP, especially when getting out the bath or working in the garden and bladder cramps.  I was referred to an endocrinologist in Apr13 to rule out chronic pancreatitis / diabetes.  A Chromogrannin A (CgA) blood test came back elevated - suspected a Neuroendocrine Tumour and was referred to a Gastroenterologist to search and find possible tumour, Gastro wanted to re-run all the previous abdominal tests, but by Oct13, I had become too 'weak' (entirely different to being tired) to redo all prior scopes and was hospitalised again in Jan 2014 - with a Dx of Lupus - methotrexate and plasmoquine treatment.  However, the heat/burn with shivers is intense and is now constant in my upper back, being worse at night - any thoughts would be appreciated...
