Hormone tests
Detailed Answer:
Sorry to learn about these disabling symptoms.
When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination:
CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
HbA1c (Glycosylated Hemoglobin = your 3 month glucose average)
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine)
TSH
Free T4
25 hydroxy Vitamin D
None of these tests require any fasting and can be done at any time of the day.
I see you have undergone a battery of tests and no specific cause for your problem is identifiable.
However running the above tests may reveal some potential reasons such as a thyroid condition or low vitamin D.
