I have been going to Dr's for a long time with extreme fatigue, vertigo, skin itching, bone pain, chest pain and palpatations. lots of blood tests all negative although I had low b12 and very low Vitamin D diagnosed around 2014.  I was told on Friday I have thick blood and borderline high haemaglobin.  Dr said I've to get further blood tests in 2 months and blood pressure checked in 1 month, as diastolic is high. I am running on empty, always wake up feeling like I have a hangover I drink lots during the day and a pint of water overnight, I don't sleep well. I am really worried because Dr is not telling me anything and I have to wait until August for further tests, is this normal.

Thank you and sorry for long post.
