Sciatica : You may have a condition called sciatica which occurs when the nerve going to your leg is pinched as it comes out of the spine to give the pain down the leg and back. Have your primary care doctor check it out to make sure your leg muscles are not getting weaker because of the nerve problem. This doctor can refer you to the appropriate specialist you need to see. Please get this checked out.

Cervical spondylosis: Pinched nerve in the neck can cause symptoms you mentioned.. Have your pcp examine.
