Injuring your Achilles tendon can be extremely painful. You use the Achilles tendon grouping a lot, for example, while standing and walking. So, an injury can be especially inconvenient because it affects nearly all of your movements.

When you think about food allergies, shoulder and knee joint pain is not a symptom that typically comes to mind. For people who suffer from arthritis or other inflammatory joint conditions, food allergies can cause a flare-up of pain caused by inflammation.

The human body has hundreds of bursa located between the bones and soft tissue, like tendons, muscles or ligaments. These small, fluid-filled, slippery sacs are responsible for reducing friction between the soft tissue and bones in the elbows, knees, hips, shoulders and ankles.

Blisters are a consequence of friction. When something rubs against the skin, it creates heat. Eventually, this heat causes one of the lower layers in the skin to breakdown, according to Billy Trolan M.D., in "Outdoor Research (OR) Blister Fighter’s Manual."

Finger movements are controlled by tendons -- connective tissue cords that attach your finger bones to muscles in your forearms. Overloading your finger tendons by lifting an item that is too heavy, or lifting too quickly can cause inflammation in these tendons, a condition broadly called tendinitis.

Foot numbness can be described as tingling or feeling as though the foot has fallen asleep. Reasons for tingling in the feet can range from a simple muscle issue to a far more serious metabolic issue or from nutrition to physical compression on the nerve.

Painful thumb joints make many daily tasks uncomfortable. Causes of thumb joint pain include various injuries and conditions that affect the bones and soft tissue. Pain may occur immediately after trauma to your thumb, or it may come on more gradually.

Sciatica is a symptom, often of a pinched nerve, rather than a condition, according to the Cleveland Clinic. Sometimes, it can feel like a bad cramp, or it may be an excruciating pain shooting down the leg that makes any position--standing or sitting--nearly impossible.

Swollen ankles are common during pregnancy or immediately following an injury, but if your ankles are swelling mainly at night, you may have an underlying medical condition.

Meniscus injuries -- tears in the shock-absorbing structure in your knee joints -- are the most common type of knee injury in people of all ages. These painful injuries often require surgery to trim frayed edges or repair tears in the meniscus. Rehab after surgery will improve movement and strength in your leg.

Heavy legs and edema in the ankles occur due to vascular insufficiency. In other words, the blood flow in the legs is not adequate.

Sometimes small calcium deposits form on or under the skin. Lesions may develop near a recent injury or surgical incision site where skin and soft tissue have been damaged. These bumps often look like firm white or yellowish papules on the surface of the skin.
