I think I had a viral illness end of November/beginning of December. I had severe exhaustion, no energy, arms and legs aches and thighs and groin were painful, headache and like a floaty sensation but not dizzy in vision. I think if might have been flu? Never had it before and this knocked me for six. I had bloods done first week in December and all came back normal but I know viral doesn’t always show up. I’m still now feeling very tired and low energy and in bed at night my chest feels a dull ache when turning over. Driving me mad
