For the past two weeks I've been suffering from lower back ache, there are some morning when I cannot put all my weight on my right leg to put my pants on and i end up having to sit on the edge of my bed to get dressed. I've suffered from pins and needles in my toes which occur even when I'm sitting, even though there is no pressure put on my toes. Some mornings, for a while i have a shooting pain down my thigh each time i step with my right leg. And last night I realized that my right big toe has gone numb and it's still there right now.I don't feel like its serious enough to go to a doctor, what would you suggest? I've had back problems for a long time and usually it goes away when I wear flat shoes for a couple of days but I've worn flat shoes since last week and it seems to be getting worse.
