"I felt I should have had more tests"

I was referred to see a Dr, because I have felt so tired these last 25 years, that I feel like a decomposed corpse.

The Dr gave me a CT scan and an MRI scan as I asked, but when they came back negative (as Myalgic Encephalomyelitis / "Chronic Fatigue Syndrome" can't be detected, something I didn't know at the time) the Dr wouldn't refer me for more tests as I think they should have, such as

1) urea & electrolytes

2) thyroid function

3) erythrocyte sedimintation rate Or plasma viscosity

4) C-reactive protein

5) random blood glucose

6) serum creatine

7) screening blood tests for gluten sensitivity

8) serum calcium

9) creatine kinase

I reported them to the NHS Ombudsman for discharging me back to my GP too early, and for not even explaining my non-complete NHS Treatment to me and not doing these tests at all.
