What Can Cause Leg Ache Along With Weakness In The Hands?

I had left leg pain , not sharp pain, more a muscle pain, but felt in the feet and big toe. had cortisone tablets, felt better but calf and ankle kept paining to the point i couldnt put my weight on that foot, having difficulty in walking. had an ultra sound, all ok. Had 2 Xray, lower leg and lower back, no broken bones. today left lower back feels very tender and that side. feel weakness in hands and that side. tired of going to Orthopedic office.
