I Have Numb Toes, Secoond, Third And Fourth, Right Foot

I have numb toes, secoond, third and fourth, right foot worse than left. I do exercise every day stressing the balls of my feet,, more pressure on right foot when hitting ground. Have had some numbness in fingers for a couple of years, mainly on waking and now experience pins and needles a few times daily for a few seconds in my legs. I am a 58 year old fit healthy lean woman working in aged care and have definitely stressed my lower back and often feel stiffness and mild pain when bending over. Thank-you for your help.
