Half leg pain and muscle cramps.

My both half leg pains whole day and when I wake up then I feel my leg knee is little heavy and pain . When I do work in sitting position or bending posture then I feel pain in my back . When I am normal then I do not feel any pain in back . I have checked my CBC , Hb , blood sugar , calcium level all is normal . But my half leg pain and back pain is not going permanently . When I take electerol powder then I feel little releif in my leg pain and after leaving then I feel again pain . Please suggest what should I do . I have consulted homeopathy doctor and after 2 months medicines his medicine has no effect on my pain and lastly he advised my for x ray of spine . Now I am not taking homeopathy medicines . Please suggest what should I do . I am attaching my doctor medicine which do not work on me please suggest .
