Following a long bout of flu, sinus infection, tooth extraction and post viral fatigue at Christmas I have continued to feel run down. I then noticed several other smaller symptoms like pins and needles, migraines, ridged nails, ringing in left ear all building to a picture of me not being quite myself.
I thought it might be Thyroid but following blood test visited Doctor today who has prescribed 6 injections of B12 in two weeks followed by further blood test and injection every three months.
What can I expect from blood test and how soon will I see results?
