I am suffering with sleep disturbances and whole body aches with dry feeling since 45 days. I visited physician. He ordered CBC, esr,crp, rh factor, testosterone, vit d, vit b total ige all negative except slightly deficiency vit d and vit b. He prescribed medicine for vit d and vit b deficiency. I have 3 weekly doses of medicine. Until now I didn't get any relief in my symptoms. May I know what can be the root cause of my symptoms. Is their any blood test need to be done to diagnose. Please advise me. I have previous complaints hypertension and diabetes. All normal in parameters including hb1ac also normal. I am so worry.
