But we're also susceptible to hundreds of injuries, diseases, and conditions. Some are quite common, others are extremely rare. Here are some of the most common conditions that affect humans.

Coping with motion sickness

The most widely accepted theory about the cause of motion sickness points to a phenomenon called sensory conflict, when the inputs of the senses don’t agree.

The piriformis muscle connects the lowermost vertebrae with the upper part of the leg after traveling the "sciatic notch," the opening in the pelvic bone that allows the sciatic nerve to travel into the leg. Here, the muscle and nerve are adjacent and this proximity is why trouble can develop. The condition is relatively common. Estimates suggest that about 5% of cases of sciatica (irritation of the sciatic nerve causing radiating pain from the back or buttock into the leg, calf and foot) are due to piriformis syndrome. It seems to be more common among women though the reason for this is not known. The typical patient with piriformis syndrome complains of "sciatica" — that is, sharp, severe, radiating pain from the lower back or buttock down the back of the leg and into the thigh, calf, and foot. Symptoms may seem to be due to hip bursitis or disc herniation ("slipped disc") but the doctor's examination helps sort out the true cause because with piriformis syndrome the person also has: More »
