Back pain: There are many causes of back pain: strain, arthritis, herniated disk, sciatica , kidney stones or infection, shingles, hip problems among many others. See physician for evaluation.

Many possibilities: Possible cause of your pain may include sprain, bursitis, fracture, contusion, neuritis, but of course there are a multitude of other possibilities. Get the feet inspected by a professional to determine the cause of the problem, as treatment varies depending on the diagnosis.

Ankle needs care: You have probably done more than just strain your back muscles with the back condition in view of the neck condition you describe. The limping makes the distribution of pressure on your back and its' nerves uneven and this can aggravate a pre existing disc and/or back arthritic problem. A major ankle sprain should be tapped and not weight bare initially. Have your ankle seen by an orthopedist.
