I'm 30 , healthy BMI 8-10 my lower back is really hurting my legs and aching feet. My shoulder arms and right hand is also aching. No temperature but headaches on and off. I've had it for around a week I even had to stop my car as my arm was hurting too much .I don't want really want to go to the NHS GP as I feel like a hypochondriac symptoms seem so vague. Does anyone know what it could be ? I had a full body massage today and still very painful.
