What causes one to experience pains on the sole i.e.back of the left foot. Any health implications for this?

I am 52 years old. This pain is usually severe in the morning when I just woke up. The shoes I wear are of right sizes and shapes.

Two things might cause you pain.As we age,the flesh on our heels gets older and thinner. We can get what is called " Heel Strike". This is where constant pressure on the heel causes continual pain.You can rectify it by getting a pair of Scholls innersoles.Cushions the heel. The other problem might be Sciatica. Usually caused by lower back pain or discomfort. Sciatica usually is felt as pain down left leg, and can go sas far as heel.Best get checked one way or another. Good Luck!

Bone spurs are one problem, the Acilles(spelled wrong)tendon being damaged is another.

Are the shoes you are wearing soft? Sometimes when the shoes you wear every day are hard and you step on your foot (without even realizing) in a straining way, this pain can be caused that is some kind of inflammation. If it is an inflammation, your doctor can prescribe some (cheap) medication or give you a rather painful shot.

Plantar Fasciitis.

The plantar fascia is a band of connective tissue that runs across the bottom of your foot. The origin is at the calcaneous (heel bone). This is a common, but aggravating problem. Caused by overuse and stress on your foot. Partial tears of the fascia are extremely frustrating because they can take a long time to heal.

This is a problem that just hurts.

Ice, arch supports, and stretching are the basics. It is very important to stretch your calf muscle (achilles tendon). Friction massage such as putting a golf ball under the sore spot and rolling your foot over it may give you a "good hurt" that helps to heal. More aggressive care by a physician may include night splints, injections, and as a last resort - surgery.
